Run "cargo fmt --all" to ensure formatting is correct. + + 9. Run "cargo clippy --workspace --tests --benches -- -D warnings" to check for issues. Fix any warnings and rerun until clean. + + 10. Run ONLY the tests related to the changes in these PRs: + - Use "git diff --name-only ${RELEASE_BRANCH}...HEAD" to see all files changed across all cherry-picked commits. + - For Rust changes: Run tests for the affected crates only (e.g., "cargo test -p lance-core" if lance-core files changed). + - For Python changes (python/** files): Build with "cd python && maturin develop" then run "pytest" on the specific test files that were modified, or related test files. + - For Java changes (java/** files): Run "cd java && mvn test" for the affected modules. + - If test files themselves were modified, run those specific tests. + - Do NOT run the full test suite - only run tests related to the changed files. + + 11. If additional guidelines are provided, follow them as well when making decisions or resolving issues. + + 12. Stage any additional changes with "git add -A" and amend the last commit if needed: "git commit --amend --no-edit". + + 13. Push the branch: "git push origin ".

-1. **Async-first Architecture**: Heavy use of tokio and async/await throughout Rust codebase -2. **Arrow-native**: All data operations work directly with Apache Arrow arrays -3. **Version Control**: Every write creates a new version with manifest tracking -4. **Indexing**: Supports both vector indices (for similarity search) and scalar indices (BTree, inverted) -5. **Encoding**: Custom encodings optimized for ML data patterns -6. **Object Store**: Unified interface for local, S3, Azure, GCS storage - -## Development Notes - -- All public APIs should have comprehensive documentation with examples -- Performance-critical code uses SIMD optimizations where available -- Always rebuild Python extension after Rust changes using `maturin develop` -- Integration tests require Docker for local S3/DynamoDB emulation -- Use feature flags to control dependencies (e.g., `datafusion` for SQL support) - -## Development tips - -Code standards: -* Be mindful of memory use: - * When dealing with streams of `RecordBatch`, avoid collecting all data into - memory whenever possible. - * Use `RoaringBitmap` instead `HashSet<u32>`. - -Tests: -* When writing unit tests, prefer using the `memory://` URI instead of creating - a temporary directory. -* Use rstest to generate parameterized tests to cover more cases with fewer lines - of code. - * Use syntax `#[case::{name}(...)]` to provide human-readable names for each case. -* For backwards compatibility, use the `test_data` directory to check in datasets - written with older library version. - * Check in a `datagen.py` that creates the test data.

Only add meaningful comments and tests. +- Comments should explain non-obvious "why" reasoning, not restate what the code does. +- Remove debug prints (`println!`, `dbg!`, `print()`) before merging — use `tracing` or logging frameworks. +- Extract logic repeated in 2+ places into a shared helper; inline single-use logic at its call site. +- Keep PRs focused — no drive-by refactors, reformatting, or cosmetic changes. +- Be mindful of memory use: avoid collecting streams of `RecordBatch` into memory; use `RoaringBitmap` instead of `HashSet<u32>`. + +### Cross-Language Bindings + +- Keep Python and Java bindings as thin wrappers — centralize validation and logic in the Rust core. +- Keep parameter names consistent across all bindings (Rust, Python, Java) — rename everywhere or nowhere. +- Never break public API signatures — deprecate with `#[deprecated]`/`@deprecated` and add a new method. +- Replace mutually exclusive boolean flags with a single enum/mode parameter. + +### Naming + +- Name variables after what the value *is* (e.g., `partition_id` not `mask`) — precise names act as inline docs. +- Drop redundant prefixes when the struct/module already implies the domain. +- Use `indices` (not `indexes`) consistently in all APIs and docs. +- Use storage-agnostic terms in API names (e.g., `base` not `bucket`). +- When renaming a type/struct/enum, update all references (methods, fields, variables, test names). + +### Error Handling + +- Validate inputs and reject invalid values with descriptive errors at API boundaries — never silently clamp or adjust. +- Validate mutually exclusive options in builders/configs — throw a clear error if both are set. +- Include full context in error messages: variable names, values, sizes, types. + +### Dependencies + +- Prefer implementing functionality with the standard library or existing workspace dependencies before adding new external crates. +- Keep `Cargo.lock` changes intentional; revert unrelated dependency bumps. Pin broken deps with a comment linking the upstream issue. +- Gate optional/domain-specific deps behind Cargo feature flags. Prefer separate crates for domain functionality (geo, NLP). + +## Testing Standards + +- **All bugfixes and features must have corresponding tests. We do not merge code without tests.** +- Use `rstest` (Rust) or `@pytest.mark.parametrize` (Python) for tests that differ only in inputs. Use `#[case::{name}(...)]` for readable case names. +- Replace `print()` in tests with `assert` — prints don't catch regressions. +- Extend existing tests instead of adding overlapping new ones. Add to existing test files. +- Link a GitHub issue when skipping a test — never bare `@pytest.mark.skip` or `@Ignore` without a tracking URL. +- Include multi-fragment scenarios for dataset operations (reads, indexes, scans). +- Cover NULL edge cases in index tests: null items, all-null collections, empty collections, null columns. +- Vector index tests must assert recall metrics (>=0.5 threshold), not just verify creation succeeds. +- For backwards compatibility, use the `test_data` directory with checked-in datasets from older versions. Include a `datagen.py` that asserts the Lance version used. Use `copy_test_data_to_tmp` to read this data. +- Avoid `ignore` in doctests — write Rust doctests that compile a function instead: ``` /// ``` /// # use lance::{Dataset, Result}; @@ -125,3 +113,20 @@ Tests: /// # } /// ``` ``` +- Skip coverage for test utilities using `#[cfg_attr(coverage, coverage(off))]`. + +## Documentation Standards + +- All public APIs must have documentation with examples.

Copyright and Related Rights. A Work made available under CC0 may be +protected by copyright and related or neighboring rights ("Copyright and +Related Rights"). Copyright and Related Rights include, but are not +limited to, the following: + + i. the right to reproduce, adapt, distribute, perform, display, + communicate, and translate a Work; + ii. moral rights retained by the original author(s) and/or performer(s); +iii. publicity and privacy rights pertaining to a person's image or + likeness depicted in a Work; + iv. rights protecting against unfair competition in regards to a Work, + subject to the limitations in paragraph 4(a), below; + v. rights protecting the extraction, dissemination, use and reuse of data + in a Work; + vi. database rights (such as those arising under Directive 96/9/EC of the + European Parliament and of the Council of 11 March 1996 on the legal + protection of databases, and under any national implementation + thereof, including any amended or successor version of such + directive); and +vii. other similar, equivalent or corresponding rights throughout the + world based on applicable law or treaty, and any national + implementations thereof. + +2. Waiver. To the greatest extent permitted by, but not in contravention +of, applicable law, Affirmer hereby overtly, fully, permanently, +irrevocably and unconditionally waives, abandons, and surrenders all of +Affirmer's Copyright and Related Rights and associated claims and causes +of action, whether now known or unknown (including existing as well as +future claims and causes of action), in the Work (i) in all territories +worldwide, (ii) for the maximum duration provided by applicable law or +treaty (including future time extensions), (iii) in any current or future +medium and for any number of copies, and (iv) for any purpose whatsoever, +including without limitation commercial, advertising or promotional +purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each +member of the public at large and to the detriment of Affirmer's heirs and +successors, fully intending that such Waiver shall not be subject to +revocation, rescission, cancellation, termination, or any other legal or +equitable action to disrupt the quiet enjoyment of the Work by the public +as contemplated by Affirmer's express Statement of Purpose. + +3. Public License Fallback. Should any part of the Waiver for any reason +be judged legally invalid or ineffective under applicable law, then the +Waiver shall be preserved to the maximum extent permitted taking into +account Affirmer's express Statement of Purpose. In addition, to the +extent the Waiver is so judged Affirmer hereby grants to each affected +person a royalty-free, non transferable, non sublicensable, non exclusive, +irrevocable and unconditional license to exercise Affirmer's Copyright and +Related Rights in the Work (i) in all territories worldwide, (ii) for the +maximum duration provided by applicable law or treaty (including future +time extensions), (iii) in any current or future medium and for any number +of copies, and (iv) for any purpose whatsoever, including without +limitation commercial, advertising or promotional purposes (the +"License"). The License shall be deemed effective as of the date CC0 was +applied by Affirmer to the Work. Should any part of the License for any +reason be judged legally invalid or ineffective under applicable law, such +partial invalidity or ineffectiveness shall not invalidate the remainder +of the License, and in such case Affirmer hereby affirms that he or she +will not (i) exercise any of his or her remaining Copyright and Related +Rights in the Work or (ii) assert any associated claims and causes of +action with respect to the Work, in either case contrary to Affirmer's +express Statement of Purpose. + +4.

Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6. Disclaimer of Warranty * +* ------------------------- * +* * +* Covered Software is provided under this License on an "as is" * +* basis, without warranty of any kind, either expressed, implied, or * +* statutory, including, without limitation, warranties that the * +* Covered Software is free of defects, merchantable, fit for a * +* particular purpose or non-infringing. The entire risk as to the * +* quality and performance of the Covered Software is with You. * +* Should any Covered Software prove defective in any respect, You * +* (not any Contributor) assume the cost of any necessary servicing, * +* repair, or correction.

This * +* limitation of liability shall not apply to liability for death or * +* personal injury resulting from such party's negligence to the * +* extent applicable law prohibits such limitation. Some * +* jurisdictions do not allow the exclusion or limitation of * +* incidental or consequential damages, so this exclusion and * +* limitation may not apply to You. * +* * +************************************************************************ + +8. Litigation +------------- + +Any litigation relating to this License may be brought only in the +courts of a jurisdiction where the defendant maintains its principal +place of business and such litigation shall be governed by laws of that +jurisdiction, without reference to its conflict-of-law provisions. +Nothing in this Section shall prevent a party's ability to bring +cross-claims or counter-claims. + +9. Miscellaneous +---------------- + +This License represents the complete agreement concerning the subject +matter hereof. If any provision of this License is held to be +unenforceable, such provision shall be reformed only to the extent +necessary to make it enforceable. Any law or regulation which provides +that the language of a contract shall be construed against the drafter +shall not be used to construe this License against a Contributor. + +10. Versions of the License +--------------------------- + +10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section +10.3, no one other than the license steward has the right to modify or +publish new versions of this License. Each version will be given a +distinguishing version number. + +10.2.

Modified Versions + +If you create software not governed by this License, and you want to +create a new license for such software, you may create and use a +modified version of this License if you rename the license and remove +any references to the name of the license steward (except to note that +such modified license differs from this License). + +10.4.

Object Store + +At the foundation lies the **object store**—storage systems characterized by their object-based simple hierarchy, +typically providing highly durable guarantees with HTTP-based communication protocols for data transfer. +This includes systems like S3, GCS, and Azure Blob Storage. + +### 2. File Format + +Above the storage layer, the **file format** describes how a single file should be stored on disk. +This is where formats like Apache Parquet operate, defining the internal structure, encoding, and compression of individual data files. + +### 3. Table Format + +The **table format** layer describes how multiple files work together to form a logical table. +The key feature that modern table formats enable is transactional commits and read isolation to allow multiple writers and readers to safely operate against the same table. +All major open source table formats including Iceberg and Lance implement these features through MVCC (Multi-Version Concurrency Control), +where each commit atomically produces a new table version, and all table versions form a serializable history for the specific table. +This also unlocks features like time travel and makes features like schema evolution easy to develop. + +### 4. Catalog Spec + +The **catalog spec** defines how any system can discover and manage a collection of tables within storage. +This is where the lower storage and format stack meets the upper service and compute stack. + +Table formats require at least a way to list all available tables and to describe, add and drop tables in the list. +This is necessary for actually building the so-called **connectors** in compute engines so they can discover and start working on the table according to the format. +Historically, Hive has defined the Hive MetaStore spec that is sufficient for most table formats including Delta Lake, Hudi, Paimon, and also Lance. +Iceberg offers its unique Iceberg REST Catalog spec. + +From the top down, projects like Apache Polaris, Unity Catalog, and Apache Gravitino usually offer additional specification for operating against table derivatives +(e.g. views, materialized views, user-defined table functions) and objects used in table operations (e.g. user-defined functions, policies). + +This intersection between top and bottom stack is also why typically a catalog service would provide both the catalog specifications offered by the format side for easy connectivity to compute engines, +as well as providing their own APIs for extended management features. + +Another key differentiation of a catalog spec versus a catalog service is that there can be multiple different vendors implementing the same spec. +For example, for Polaris REST spec we have open source Apache Polaris server, Snowflake Horizon Catalog, and Polaris-compatible services in AWS Glue, Azure OneLake, etc. + +### 5. Catalog Service + +A **catalog service** implements one or more catalog specifications to provide both table metadata and optionally continuous background maintenance (compaction, optimization, index updates) that table formats require to stay performant. +Catalog services typically implement multiple specifications to support different table formats. +For example, Polaris, Unity and Gravitino all support the Iceberg REST catalog specification for Iceberg tables, and have their own generic table API for other table formats. + +Since table formats are static specifications, catalog services supply the active operational work needed for production deployments. +This is often where open source transitions to commercial offerings, as open source projects typically provide metadata functionality, while commercial solutions offer the full operational experience including automated maintenance. +There are also open source solutions like Apache Amoro emerging to fill this gap with complete open source catalog service implementations that offer both table metadata access and continuous optimization. + +### 6. Compute Engine + +Finally, **compute engines** are the workhorses that visit catalog services and leverage their knowledge of file formats, table formats, and catalog specifications to perform complex data workflows, including SQL queries, analytics processing, vector search, full-text search, and machine learning training. +All sorts of applications can be built on top of compute engines to serve more concrete analytics, ML and AI use cases. + +### The Overall Lakehouse Architecture + +In the lakehouse architecture, compute power resides in the object store, catalog services, and compute engines. +The middle three layers (file format, table format, catalog spec) are specifications without compute. +This separation enables portability and interoperability. + +## Understanding Lance as a Lakehouse Format + +Lance spans all three specification layers: + +1. **File Format**: The Lance columnar file format, [read specification →](file/index.md) +2. **Table Format**: The Lance table format, [read specification →](table/index.md) +3. **Catalog Spec**: The Lance Namespace specification, [read specification →](namespace/index.md) + +For comparison: + +- **Apache Iceberg** operates at the table format and catalog spec layers, using Apache Parquet, Apache Avro and Apache ORC as the file format +- **Delta Lake** and **Apache Hudi** operate at only the table format layer, using Apache Parquet as the file format \ No newline at end of file diff --git a/docs/src/format/table/.pages b/docs/src/format/table/.pages index 94701b5a1b4..eb065fd91cd 100644 --- a/docs/src/format/table/.pages +++ b/docs/src/format/table/.pages @@ -1,3 +1,10 @@ nav: - index.md + - Schema: schema.md + - Versioning: versioning.md + - Transactions: transaction.md + - Layout: layout.md + - Branch & Tag: branch_tag.md + - Row ID & Lineage: row_id_lineage.md + - MemTable & WAL: mem_wal.md - index diff --git a/docs/src/format/table/branch_tag.md b/docs/src/format/table/branch_tag.md new file mode 100644 index 00000000000..e3bd328d5d2 --- /dev/null +++ b/docs/src/format/table/branch_tag.md @@ -0,0 +1,121 @@ +# Branch and Tag Specification + +## Overview + +Lance supports branching and tagging for managing multiple independent version histories and creating named references to specific versions. +Branches enable parallel development workflows, while tags provide stable named references for important versions. + +## Branching + +### Branch Name + +Branch names must follow these validation rules: + +1.

This is described in the [protos/rowids.proto](https://github.com/lancedb/lance/blob/main/protos/rowids.proto) file. Row ID sequences are just arrays of u64 values, which have representations optimized for the common case where they are sorted and possibly contiguous. For example, a new fragment will have a row ID sequence that is just a simple range, so it is stored as a `start` and `end` value. +See [Transaction Specification](transaction.md) -These sequence messages are either stored inline in the fragment metadata, or are written to a separate file and referenced from the fragment metadata. This choice is typically made based on the size of the sequence. If the sequence is small, it is stored inline. If it is large, it is written to a separate file. By keeping the small sequences inline, we can avoid the overhead of additional IO operations. +### Row Lineage -```protobuf -oneof row_id_sequence { - // Inline sequence - bytes inline_sequence = 1; - // External file reference - string external_file = 2; -} // row_id_sequence -``` +Row address, Stable row ID, row version tracking, and change data feed. -### Row ID Index +See [Row ID & Lineage Specification](row_id_lineage.md) -To ensure fast access to rows by their row ID, a secondary index is created that maps row IDs to their locations in the table. This index is built when a table is loaded, based on the row ID sequences in the fragments. For example, if fragment 42 has a row ID sequence of `[0, 63, 10]`, then the index will have entries for `0 -> (42, 0)`, `63 -> (42, 1)`, `10 -> (42, 2)`. The exact form of this index is left up to the implementation, but it should be optimized for fast lookups. +### Indices -### Row ID masks +Vector indices, scalar indices, full-text search, and index management. -Because index files are immutable, they main contain references to row IDs that have been deleted or that have new values. -To handle this, a mask is created for the index. +See [Index Specification](index/index.md) -![Index and Row ID marks](../../images/stable_row_id_indices.png) +### Versioning -For example, consider the sequence shown in the above image. -It has a dataset with two columns, `str` and `vec`. -A string column and a vector column. -Each of them have indices, a scalar index for the string column and a vector index for the vector column. -There is just one fragment in the dataset, with contiguous row IDs 1 through 3. +Feature flags and format version compatibility. -When an update operation is made that modifies the `vec` column in row 2, a new fragment is created with the updated value. -A deletion file is added to the original fragment marking that row 2 as deleted in the first file. -In the `str` index, the fragment bitmap is updated to reflect the new location of the row IDs:`{1, 2}`. -Meanwhile, the `vec` index's fragment bitmap does not update, staying at `{1}`. -This is because the value in `vec` was updated, so the data in the index no longer reflects the data in the table. +See [Format Versioning Specification](versioning.md) diff --git a/docs/src/format/table/index/index.md b/docs/src/format/table/index/index.md index dcd572638ee..5f71d53086b 100644 --- a/docs/src/format/table/index/index.md +++ b/docs/src/format/table/index/index.md @@ -1,24 +1,163 @@ # Indices in Lance -Lance supports three main categories of indices to accelerate data access: +Lance supports three main categories of indices to accelerate data access: scalar +indices, vector indices, and system indices. + +**Scalar indices** are traditional indices that speed up queries on scalar data types, such as +integers and strings. Examples include [B-trees](scalar/btree.md) and +[full-text search indices](scalar/fts.md). Typically, scalar indices receive a +query predicate, such as equality or range conditions, and output a set of row addresses that +satisfy the predicate. + +<figure markdown="span"> + ![](./scalar_index.drawio.svg) +</figure> + +**[Vector indices](./vector/index.md)** are specialized for approximate nearest neighbor (ANN) search on high-dimensional +vector data, such as embeddings from machine learning models. Examples includes IVF (Inverted File) +indices and HNSW (Hierarchical Navigable Small World) indices. These are separate from scalar indices +because they use meaningfully different query patterns. Instead of sargable predicates, vector indices +receive a query vector and return the nearest neighbor row addresses based on some distance metric, +such as Euclidean distance or cosine similarity. They return row addresses and the corresponding distances. + +**System indices** are auxiliary indices that help accelerate internal system operations. They are +different from user-facing scalar and vector indices, as they are not directly used in user queries. +Examples include the [Fragment Reuse Index](system/frag_reuse.md), which supports efficient row address +remapping after compaction. + +## Design + +Lance indices are designed with the following design choices in mind: + +1. **Indices are loaded on demand**: A dataset can be loaded and read without loading any indices. + Indices are only loaded when a query can benefit from them. + This design minimizes memory usage and speeds up dataset opening time. +2. **Indices can be loaded progressively**: indices are designed so that only the necessary parts + are loaded into memory during query execution. For example, when querying a B-tree index, + it loads a small page table to figure out which pages of the index to load for the given query, + and then only loads those pages to perform the indexed search. This amortizes the cost of + cold index queries, since each query only needs to load a small portion of the index. +3. **Indices can be coalesced to larger units than fragments.** Indices are much smaller than + data files, so it is efficient to coalesce index segments to cover multiple fragments. + This reduces the number of index files that need to be opened during query execution and + then number of unique index data structures that need to be queried. +4. **Index files are immutable once written, similar to data files.** They can be modified only + by creating new files. This means they can be safely cached in memory or on disk without + worrying about consistency issues. + +## Basic Concepts + +An index in Lance is defined over a specific column (or multiple columns) of a dataset. +It is identified by its name. + +An index is made up of multiple **index segments**, identified by their unique UUIDs. +Each segment is an independent, self-contained index covering a subset of the data. + +Each index segment covers a disjoint subset of fragments in the dataset. The segments must cover +all rows in the fragments they cover, with one exception: if a fragment has delete markers at the time +of index creation, the index segment is allowed to not contain the deleted rows. The fragments an index +covers are those recorded in the `fragment_bitmap` field. + +Index segments together **do not** need to cover all fragments. This means an index isn't required to +be fully up-to-date. When this happens, engines can split their queries into indexed and unindexed +subplans and merge the results. + +<figure markdown="span"> + ![](./starter-example.drawio.svg) + <figcaption>Abstract layout of a typical dataset, with three fragments and two indices. + </figcaption> +</figure> + +Consider the example dataset in the figure above: + +- The dataset contains three fragments with ids 0, 1, 2.

Fragment 2 is not covered by the index. Queries using this index will need to query both + segments and then scan fragment 2 directly. Additionally, when querying the segment covering fragment 1, + the engine will need to filter out the 10 deleted rows. +- There is another index called "vec_idx", which has a single segment covering all three fragments. + Because it covers all fragments, queries using this index do not need to scan any fragments directly. + They do, however, need to filter out the 10 deleted rows from fragment 1. -1. **Scalar Indices** - Traditional indices for accelerating various database query patterns -2. **Vector Indices** - Specialized indices for vector search -3. **System Indices** - Auxiliary indices for accelerating internal system operations +## Index Storage -## Index Section in Manifest +The content of each index is stored at the `_indices/{UUID}` directory under the [base path](../layout.md#base-path-system). +We call this location the **index directory**. +The actual content stored in the index directory depends on the index type.

This is done atomically using the same transaction mechanism + as data writes. + +When updating an indexed column in place (without deleting the row), the engine must +remove the affected fragment IDs from the `fragment_bitmap` field of any index segments +that cover those fragments. This marks those fragments as needing re-indexing without +invalidating the entire segment and prevents invalid data from being read from the index. + +## Index Compatibility + +Before using an index segment, engines must verify they support it: + +1. **Check the index type**: The `index_details` field contains a protobuf `Any` message + whose type URL identifies the index type (e.g., B-tree, IVF, HNSW).

If the engine does not support this version, it should + skip this index segment.

Fewer, larger partitions improve query performance. | + +### Memory and Performance Considerations + +Memory usage is primarily determined by two factors: + +- **`LANCE_FTS_NUM_SHARDS`** -- Each worker holds an independent in-memory buffer. Peak memory is roughly `NUM_SHARDS * PARTITION_SIZE` plus the overhead of token dictionaries and posting list structures. +- **`LANCE_FTS_PARTITION_SIZE`** -- Larger values reduce the number of part files and make the merge phase cheaper. Smaller values reduce per-worker memory at the cost of more part files. + +Merge phase memory is bounded by the streaming approach: part files are loaded one at a time with a small concurrency buffer. The merged partition's in-memory size is bounded by `LANCE_FTS_TARGET_SIZE`. + +Building an FTS index requires temporary disk space to store the part files generated during tokenization. The amount of temporary space depends heavily on whether position information is enabled. An index with `with_position: true` stores the position of every token occurrence in every document, which can easily require 10x the size of the original column or more in temporary disk space. An index without positions tends to be smaller than the original column and will typically need less than 2x the size of the column in total disk space. + +Performance tips: + +- Larger `LANCE_FTS_TARGET_SIZE` produces fewer output partitions, which is beneficial for query performance because queries must scan every partition's token dictionary. When memory allows, prefer fewer, larger partitions. +- `with_position: true` significantly increases index size because term positions are stored for every occurrence. Only enable it when phrase queries are needed. +- The ngram tokenizer generates many more tokens per document than word-level tokenizers, so expect larger index sizes and higher memory usage. + +### Distributed Training + +The FTS index supports distributed training where different worker nodes each index a subset of the data and the results are assembled afterward. + +1. Each distributed worker is assigned a **fragment mask** (`(fragment_id as u64) << 32`) that is OR'd into the partition IDs it generates, ensuring globally unique IDs across workers. +2. Workers set `skip_merge: true` so they write their part files directly without running the merge phase. +3. Instead of a single `metadata.lance`, each worker writes per-partition metadata files named `part_<id>_metadata.lance`. +4. After all workers finish, a coordinator merges the metadata files: it collects all partition IDs, remaps them to a sequential range starting from 0 (renaming the corresponding data files), and writes the final unified `metadata.lance`. + +This allows each worker to operate independently during the tokenization phase. Only the final metadata merge requires a single-node step, and it is lightweight since it only renames files and writes a small metadata file. + ## Accelerated Queries Lance SDKs provide dedicated full text search APIs to leverage the FTS index capabilities. diff --git a/docs/src/format/table/index/scalar/label_list.md b/docs/src/format/table/index/scalar/label_list.md index 13c88d39d56..1c5cb5cdaa1 100644 --- a/docs/src/format/table/index/scalar/label_list.md +++ b/docs/src/format/table/index/scalar/label_list.md @@ -17,16 +17,17 @@ The label list index uses a bitmap index internally and stores its data in: ### File Schema -| Column | Type | Nullable | Description | -|-----------|------------|----------|---------------------------------------------------------------------| -| `keys` | {DataType} | true | The unique label value from the indexed column | -| `bitmaps` | Binary | true | Serialized RowIdTreeMap containing row IDs where this label appears | +| Column | Type | Nullable | Description | +|-----------|------------|----------|------------------------------------------------------------------------| +| `keys` | {DataType} | true | The unique label value from the indexed column | +| `bitmaps` | Binary | true | Serialized RowAddrTreeMap containing row addr where this label appears | ## Accelerated Queries The label list index provides exact results for the following query types: -| Query Type | Description | Operation | Result Type | -|----------------------|----------------------------------------|---------------------------------------------|-------------| -| **array_has_all** | Array contains all specified values | Intersects bitmaps for all specified labels | Exact | -| **array_has_any** | Array contains any of specified values | Unions bitmaps for all specified labels | Exact | \ No newline at end of file +| Query Type | Description | Operation | Result Type | +|-------------------------------------|----------------------------------------|---------------------------------------------|-------------| +| **array_has / array_contains** | Array contains the specified value | Bitmap lookup for a single label | Exact | +| **array_has_all** | Array contains all specified values | Intersects bitmaps for all specified labels | Exact | +| **array_has_any** | Array contains any of specified values | Unions bitmaps for all specified labels | Exact | diff --git a/docs/src/format/table/index/scalar/rtree.md b/docs/src/format/table/index/scalar/rtree.md new file mode 100644 index 00000000000..936eb424ec6 --- /dev/null +++ b/docs/src/format/table/index/scalar/rtree.md @@ -0,0 +1,124 @@ +# R-Tree Index + +The R-Tree index is a static, immutable 2D spatial index.

It stores: + +- **Configuration**: Region specs defining how rows map to regions, and which indexes to maintain +- **Merge progress**: Last generation merged to base table for each region +- **Index catchup progress**: Which merged generation each base table index has been rebuilt to cover +- **Region snapshots**: Snapshot of all region states for read optimization + +The index is the source of

region manifest. + +See [MemWAL Index Details](#memwal-index-details) for the complete structure. + +## Region Architecture + +![Region Architecture](../../images/mem_wal_regional.png) + +Within a region, writes are stored in an **in-memory table (MemTable)**. +It is also written to the region's **Write-Ahead Log (WAL)** for durability guarantee. +The MemTable is periodically **flushed** to storage based on memory pressure and other conditions. +**Flushed MemTables** in storage are then asynchronously **merged** into the base table. + +### MemTable + +A MemTable holds rows inserted into the region before flushing to storage. +It serves 2 purposes: + +1. build up data and related indexes to be flushed to storage as a flushed MemTable +2. allow a reader to potentially access data that is not flushed to storage yet + +#### MemTable Format + +The complete in-memory format of a MemTable is implementation-specific and out of the scope of this spec. +The Lance core Rust SDK maintains one default implementation and is available through all its language binding SDKs, +but integrations are free to build their own MemTable format depending on the specific use cases, +as long as it follows the MemWAL storage layout, reader and writer requirements when flushing MemTable. + +Conceptually, because Lance uses [Arrow as its in-memory data exchange format](https://arrow.apache.org/docs/format/index.html), +for the ease of explanation in this spec, we will treat MemTable as a list of Arrow record batches, +and each write into the MemTable is a new Arrow record batch. + +#### MemTable Generation + +Based on conditions like memory limit and durability requirements, +a MemTable needs to be **flushed** to storage and discarded. +When that happens, new writes go to a new MemTable and the cycle repeats. +Each MemTable is assigned a monotonically increasing generation number starting from 1. +When MemTable of generation `N` is discarded, the next MemTable gets assigned generation `N+1`. + +### WAL + +WAL serves as the durable storage of all MemTables in a region. +It consists of data in MemTables ordered by generation. +Every time we write to the WAL, we call it a **WAL Flush**. + +#### WAL Durability + +When a write is flushed to WAL, the specific write becomes durable. +Otherwise, if the MemTable is lost, data is also lost. + +Multiple writes can be batched together in a single WAL flush to reduce WAL flush frequency and improve throughput. +The more writes a single WAL flush batches, the longer it takes for a write to be durable. + +The whole LSM tree's durability is determined by the durability of the WAL. +For example, if WAL is stored in Amazon S3, it has 99.999999999% durability. +If it is stored in local disk, the data will be lost if the local disk is damaged. + +#### WAL Entry + +Each time a WAL flush happens, it adds a new **WAL Entry** to the WAL. +In other words, a WAL consists of an ordered list of WAL entries starting from position 0. +Writer must flush WAL entries in sequential order from lower to higher position. +If WAL entry `N` is not flushed fully, WAL entry `N+1` must not exist in storage. + +#### WAL Replay + +**Replaying** a WAL means to read data in the WAL from a lower to a higher position. +This is commonly used to recover the latest MemTable after it is lost, +by reading from the start position of the latest MemTable generation till the highest position in the WAL, +assuming proper fencing to guard against multiple writers to the same region. + +See [Writer Fencing](#writer-fencing) for the full fencing mechanism. + +#### WAL Entry Format + +Each WAL entry is a file in storage following the [Apache Arrow IPC stream format](https://arrow.apache.org/docs/format/Columnar.html#ipc-streaming-format) to store the batch of writes in the MemTable. +The writer epoch is stored in the stream's Arrow schema metadata with key `writer_epoch` for fencing validation during replay. + +#### WAL Storage Layout + +Each WAL entry is stored within the WAL directory of the region located at `_mem_wal/{region_id}/wal`. + +WAL files use bit-reversed 64-bit binary naming to distribute files evenly across the directory keyspace. +This optimizes S3 throughput by spreading sequential writes across S3's internal partitions, minimizing throttling. +The filename is the bit-reversed binary representation of the entry ID with suffix `.lance`. +For example, entry ID 5 (binary `000...101`) becomes `1010000000000000000000000000000000000000000000000000000000000000.arrow`. + +### Flushed MemTable + +A flushed MemTable is created by flushing the MemTable to storage. +In Lance MemWAL spec, a flushed MemTable must be a Lance table following the Lance table format spec. + +!!!note +This is called Sorted String Table (SSTable) or Sorted Run in many LSM-tree literatures and implementations. +However, since our MemTable is not sorted, we just use the term flushed MemTable to avoid confusion. + +#### Flushed MemTable Storage Layout + +The MemTable of generation `i` is flushed to `_mem_wal/{region_uuid}/{random_hex}_gen_{i}/` directory, +where `{random_hex}` is a random 8-character hex value generated at flush time. +The random hex value is necessary to ensure if one MemTable flush attempt fails, +The retry can use another directory. +The content within the generation directory follows the [Lance table storage layout](layout.md). + +#### Merging MemTable to Base Table + +Generation numbers determine merge order of flushed MemTable into base table: +lower numbers represent older data and must be merged to the base table first to preserve correct upsert semantics. + +Within a single flushed MemTable, if there are multiple rows of the same primary key, +the row that is last inserted wins. + +### Region Manifest + +Each region has a manifest file. This is the source of truth for the state of a region. + +#### Region Manifest Contents + +The manifest contains: + +- **Fencing state**: `writer_epoch` as the latest writer fencing token, see [Writer Fencing](#writer-fencing) for more details. +- **WAL pointers**: `replay_after_wal_entry_position` (last entry position flushed to MemTable, 0-based), `wal_entry_position_last_seen` (last entry position seen at manifest update, 0-based) +- **Generation trackers**: `current_generation` (next generation to flush), `flushed_generations` list of generation number and directory path pairs (e.g., generation 1 at `a1b2c3d4_gen_1`) + +Note: `wal_entry_position_last_seen` is a hint that may be stale since it's not updated on WAL write. +It is updated opportunistically by any reader that can update the region manifest. +The manifest itself is atomically written, but recovery must try to get newer WAL files to find the actual state beyond this hint. + +The manifest is serialized as a protobuf binary file using the `RegionManifest` message. + +<details> +<summary>RegionManifest protobuf message</summary> + +```protobuf +%%% mem_wal.message.RegionManifest %%% +``` + +</details> + +#### Region Manifest Versioning + +Manifests are versioned starting from 1 and immutable. +Each update creates a new manifest file at the next version number. +Updates use put-if-not-exists or file rename to ensure atomicity depending on the storage system. +If two processes compete, one wins and the other retries. + +To commit a manifest version: + +1. Compute the next version number +2. Write the manifest to `{bit_reversed_version}.binpb` using put-if-not-exists +3. In parallel best-effort write to `version_hint.json` with `{"version": <new_version>}` (failure is acceptable) + +To read the latest manifest version: + +1. Read `version_hint.json` to get the latest version hint. If not found, start from version 1 +2. Check existence for subsequent versions from the starting version +3. Continue until a version is not found +4. The latest version is the last found version + +!!!note +This works because the write rate to region manifests is significantly lower than read rates.

All maintained indexes have caught up (`generation <= min(index_catchup[I].caught_up_generation)`) +3. No retained base table version references the generation for time travel + +## Reader Expectations + +### LSM Tree Merging Read + +Readers **MUST** merge results from multiple data sources (base table, flushed MemTables, in-memory MemTables) by primary key to ensure correctness. + +When the same primary key exists in multiple sources, the reader must keep only the newest version based on: + +1. **Generation number** (`_gen`): Higher generation wins. The base table has generation 0, MemTables have positive integers starting from 1. +2. **Row address** (`_rowaddr`): Within the same generation, higher row address wins (later writes within a batch overwrite earlier ones). + +The ordering for "newest" is: highest `_gen` first, then highest `_rowaddr`. + +This deduplication is essential because: + +- A row updated in a MemTable also exists (with older data) in the base table +- A flushed MemTable that has been merged to the base table may not yet be garbage collected, causing the same row to appear in both +- A single write batch may contain multiple updates to the same primary key + +Without proper merging, queries would return duplicate or stale rows. + +### Reader Consistency + +Reader consistency depends on two factors: + +1. access to in-memory MemTables +2. the source of region metadata (either through MemWAL index or region manifests) + +Strong consistency requires access to in-memory MemTables for all regions involved in the query and reading region manifests directly. +Otherwise, the query is eventually consistent due to missing unflushed data or stale MemWAL Index snapshots. + +!!!note +Reading a stale MemWAL Index does not impact correctness, only freshness: + + - **Merged MemTable still in index**: If a flushed MemTable has been merged to the base table but still shows in the MemWAL index, readers query both. This results in some inefficiency for querying the same data twice, but [LSM-tree merging](#lsm-tree-merging-read) ensures correct results since both contain the same data. The inefficiency is also compensated by the fact that the data is covered by index and we rarely end up scanning both data. + - **Garbage collected MemTable still in index**: If a flushed MemTable has been garbage collected, but is still in the MemWAL index, readers would fail to open it and skip it. This is also safe because if it is garbage collected, the data must already exist in the base table. + - **Newly flushed MemTable not in index**: If a newly flushed MemTable is added after the snapshot was built, it is not queried. The result is eventually consistent but correct for the snapshot's point in time. + +### Query Planning + +#### MemTable Collection + +The query planner collects datasets from multiple sources and assembles them for unified query execution. +Datasets come from: + +1. base table (representing already-merged data) +2. flushed MemTables (persisted but not yet merged) +3. optionally in-memory MemTables (if accessible). + +Each dataset is tagged with a generation number: 0 for the base table, and positive integers for MemTable generations. +Within a region, the generation number determines data freshness, with higher numbers representing newer data. +Rows from different regions do not need deduplication since each primary key maps to exactly one region. + +The planner also collects bloom filters from each generation for staleness detection during search queries. + +#### Region Pruning + +Before executing queries, if region spec is available, +the planner evaluates filter predicates against region specs to determine which regions may contain matching data. +This pruning step reduces the number of regions to scan. + +For each filter predicate: + +1. Extract predicates on columns used in region specs +2. Evaluate which region values can satisfy the predicate +3. Prune regions whose values cannot match + +For example, with a region spec using `bucket(user_id, 10)` and a filter `user_id = 123`: + +1. Compute `bucket(123, 10) = 3` +2. Only scan regions with bucket value 3 +3. Skip all other regions + +Region pruning applies to both scan queries and prefilters in search queries. + +#### Indexed Read Plan + +When data is merged from a flushed MemTable to the base table, the base table's indexes are rebuilt asynchronously by the base table index builders. +During this window, the merged data exists in the base table but is not yet covered by the base table's indexes. + +Without special handling, indexed queries would fall back to expensive full scans for the unindexed part of the base table. +To maintain indexed read performance, the query planner should use `index_catchup` progress to determine the optimal data source for each query. + +The key insight is that flushed MemTables serve as a bridge between the base table's index catchup and the current merged state. +For a query that requires a specific index for acceleration, when `index_gen < merged_gen`, +the generations in the gap `(index_gen, merged_gen]` have data already merged in the base table but are not covered by the base table's index. +Since flushed MemTables contain pre-built indexes (created during [MemTable flush](#flushed-memtable)), queries can use these indexes instead of scanning unindexed data in the base table. +This ensures all reads remain indexed regardless of how far behind the async index builder is. + +## Appendices + +### Appendix 1: Writer Fencing Example + +This example demonstrates how epoch-based fencing prevents data corruption when two writers compete for the same region. + +#### Initial State + +``` +Region manifest (version 1): + writer_epoch: 5 + replay_after_wal_entry_position: 10 + wal_entry_position_last_seen: 12 +``` + +#### Scenario + +| Step | Writer A | Writer B | Manifest State | +| ---- | --------------------------------------------- | ----------------------------------------- | ------------------ | +| 1 | Loads manifest, sees epoch=5 | | epoch=5, version=1 | +| 2 | Increments to epoch=6, writes manifest v2 | | epoch=6, version=2 | +| 3 | Starts writing WAL entries 13, 14, 15 | | | +| 4 | | Loads manifest v2, sees epoch=6 | epoch=6, version=2 | +| 5 | | Increments to epoch=7, writes manifest v3 | epoch=7, version=3 | +| 6 | | Starts writing WAL entries 16, 17 | | +| 7 | Tries to flush MemTable, loads manifest | | | +| 8 | Sees epoch=7, but local epoch=6 | | | +| 9 | **Writer A is fenced!** Aborts all operations | | | +| 10 | | Continues writing normally | epoch=7, version=3 | + +#### What Happens to Writer A's WAL Entries? + +Writer A wrote WAL entries 13, 14, 15 with `writer_epoch=6` in their schema metadata. + +When Writer B performs crash recovery or MemTable flush: + +1.

Reads each file's `writer_epoch` from schema metadata +6. Entries 13, 14, 15 have `writer_epoch=6` which is <= current epoch (7) -> **valid, will be replayed** +7. Entries 16, 17 have `writer_epoch=7` -> **valid, will be replayed** + +#### Key Points + +1. **No data loss**: Writer A's entries are not discarded. They were written with a valid epoch at the time and will be included in recovery. + +2. **Consistency preserved**: Writer A is prevented from making further writes that could conflict with Writer B. + +3. **Orphaned files are safe**: WAL files from fenced writers remain on storage and are replayed by the new writer. They are only garbage collected after being included in a flushed MemTable that has been merged. + +4. **Epoch validation timing**: Writers check their epoch before manifest updates (MemTable flush), not on every WAL write. This keeps the hot path fast while ensuring consistency at commit boundaries. + +### Appendix 2: Concurrent Merger Example + +This example demonstrates how MemWAL Index and conflict resolution handle concurrent mergers safely. + +#### Initial State + +``` +MemWAL Index: + merged_generations: {region: 5} + +Region manifest (version 1): + current_generation: 8 + flushed_generations: [(6, "abc123_gen_6"), (7, "def456_gen_7")] +``` + +#### Scenario 1: Racing on the Same Generation + +Two mergers both try to merge generation 6 concurrently. + +| Step | Merger A | Merger B | MemWAL Index | +| ---- | ------------------------- | ------------------------------ | ---------------- | +| 1 | Reads index: merged_gen=5 | | merged_gen=5 | +| 2 | Reads region manifest | | | +| 3 | Starts merging gen 6 | | | +| 4 | | Reads index: merged_gen=5 | merged_gen=5 | +| 5 | | Reads region manifest | | +| 6 | | Starts merging gen 6 | | +| 7 | Commits (merged_gen=6) | | **merged_gen=6** | +| 8 | | Tries to commit | | +| 9 | | **Conflict**: reads new index | | +| 10 | | Sees merged_gen=6 >= 6, aborts | | +| 11 | | Reloads, continues to gen 7 | | + +Merger B's conflict resolution detected that generation 6 was already merged by checking the MemWAL Index in the conflicting commit. + +#### Scenario 2: Crash After Table Commit + +Merger A crashes after committing to the table. + +| Step | Merger A | Merger B | MemWAL Index | +| ---- | ------------------------- | -------------------------------- | ---------------- | +| 1 | Reads index: merged_gen=5 | | merged_gen=5 | +| 2 | Merges gen 6, commits | | **merged_gen=6** | +| 3 | **CRASH** | | merged_gen=6 | +| 4 | | Reads index: merged_gen=6 | merged_gen=6 | +| 5 | | Reads region manifest | | +| 6 | | **Skips gen 6** (already merged) | | +| 7 | | Merges gen 7, commits | **merged_gen=7** | + +The MemWAL Index is the single source of truth.

However, a fragment reuse index or the stable row ids feature can allow these operations to be compatible. + +Several operations modify existing fragments. As a result, they can potentially conflict with Rewrite if they modify +the same fragments. However, Merge is [overly general](#overly-general-operation) and so no conflict detection is possible. +As a result, here are the operations that are retryable conflicts with Rewrite: + +- Merge (always) +- DataReplacement (only if overlapping fragments) +- Delete (only if overlapping fragments) +- Update (only if overlapping fragments) +- Rewrite (if overlapping fragments or both carry a fragment reuse index) +- CreateIndex (overlapping fragments and no fragment reuse index or stable row ids) + +There is one case where a Rewrite will rebase.

If possible, +more restrictive operations such as Rewrite, DataReplacement, or Append should be preferred over Merge. + +#### Merge Compatibility + +As mentioned above, Merge is a very generic operation, as a result it has a high potential for conflicts with other operations. +The following operations conflict with Merge: + +- Overwrite +- Restore +- UpdateMemWalState +- Project + +These operations are retryable conflicts with Merge: + +- Update (always) +- Append (always) +- Delete (always) +- Merge (always) +- Rewrite (always) +- DataReplacement (always) + +### Project + +Removes columns from the table, modifying the schema. +This is a metadata-only operation; data files are not modified. + +<details> +<summary>Project protobuf message</summary> + +```protobuf +%%% proto.message.Project %%% +``` + +</details> + +#### Project Compatibility + +Since project only modifies the schema, it is compatible with most other operations.

It's generally assumed this trumps any +other operation. Here are the operations that conflict with Restore: + +- UpdateMemWalState + +### ReserveFragments + +Pre-allocates fragment IDs for use in future `Rewrite` operations. +This allows rewrite operations to reference fragment IDs before the rewrite transaction is committed. + +<details> +<summary>ReserveFragments protobuf message</summary> + +```protobuf +%%% proto.message.ReserveFragments %%% +``` + +</details> + +#### ReserveFragments Compatibility + +The ReserveFragments operation is fairly trivial. The only thing it changes is the max fragment id. So this +only conflicts with operations that modify the max fragment id. Here are the operations that conflict with ReserveFragments: + +- Overwrite +- Restore + +### Clone + +Creates a shallow or deep copy of the table. +Shallow clones are metadata-only copies that reference original data files through `base_paths`. +Deep clones are full copies using object storage native copy operations (e.g., S3 CopyObject). + +<details> +<summary>Clone protobuf message</summary> + +```protobuf +%%% proto.message.Clone %%% +``` + +</details> + +#### Clone Compatibility + +The Clone operation can only be the first operation in a dataset.

Like a Delete operation, it will modify fragments to change +the deletion mask. As a result, there will be a retryable conflict with other operations that modify the same fragments. +Here are the operations that are retryable conflicts with Update: + +- Rewrite (only if overlapping fragments) +- DataReplacement (only if overlapping fragments) +- Merge (always) + +Similar to Delete, the Update operation can rebase other modifications to the deletion mask.

As a result, it can be safer and simpler than Merge +or Update operations. Here are the operations that conflict with DataReplacement: + +- Overwrite +- Restore +- UpdateMemWalState + +The following operations are retryable conflicts with DataReplacement: + +- DataReplacement (only if same field and overlapping fragments) +- CreateIndex (only if the field being replaced is being indexed) +- Rewrite (only if overlapping fragments) +- Update (only if overlapping fragments) +- Merge (always) + +### UpdateMemWalState + +Updates the state of MemWal indices (write-ahead log based indices). + +<details> +<summary>UpdateMemWalState protobuf message</summary> + +```protobuf +%%% proto.message.UpdateMemWalState %%% +``` + +</details> + +### UpdateBases + +Adds new base paths to the table, enabling reference to data files in additional locations. + +<details> +<summary>UpdateBases protobuf message</summary> + +```protobuf +%%% proto.message.UpdateBases %%% +``` + +</details> + +#### UpdateBases Compatibility + +An UpdateBases operation only modifies the base paths. As a result, it only conflicts with other +UpdateBases operations and even then only conflicts if the two operations have base paths with the +same id, name, or path. + +## Conflict Resolution + +### Terminology + +When concurrent transactions attempt to commit against the same read version, Lance employs conflict resolution to determine whether the transactions can coexist. +Three outcomes are possible: + +- **Rebasable**: The transaction can be modified to incorporate concurrent changes while preserving its semantic intent. + The transaction is transformed to account for the concurrent modification, then the commit is retried automatically within the commit layer. + +- **Retryable**: The transaction cannot be rebased, but the operation can be re-executed at the application level with updated data. + The implementation returns a retryable conflict error, signaling that the application should re-read the data and retry the operation. + The retried operation is expected to produce semantically equivalent results. + +- **Incompatible**: The transactions conflict in a fundamental way where retrying would violate the operation's assumptions or produce semantically different results than expected. + The commit fails with a non-retryable error. + Callers should proceed with extreme caution if they decide to retry, as the transaction may produce different output than originally intended. + +### Rebase Mechanism + +The `TransactionRebase` structure tracks the state necessary to rebase a transaction against concurrent commits: + +1. **Fragment tracking**: Maintains a map of fragments as they existed at the transaction's read version, marking which require rewriting +2. **Modification detection**: Tracks the set of fragment IDs that have been modified or deleted +3. **Affected rows**: For Delete and Update operations, stores the specific rows affected by the operation for fine-grained conflict detection +4. **Fragment reuse indices**: Accumulates fragment reuse index metadata from concurrent Rewrite operations + +When a concurrent transaction is detected, the rebase process: + +1. Compares fragment modifications to determine if there is overlap +2. For Delete/Update operations, compares `affected_rows` to detect whether the same rows were modified +3. Merges deletion vectors when both transactions delete rows from the same fragment +4. Accumulates fragment reuse index updates when concurrent Rewrites change fragment IDs +5. Modifies the transaction if rebasable, or returns a retryable/incompatible conflict error + +### Conflict Scenarios + +#### Rebasable Conflict Example + +The following diagram illustrates a rebasable conflict where two Delete operations modify different rows in the same fragment: + +```mermaid +gitGraph + commit id: "v1" + commit id: "v2" + branch writer-a + branch writer-b + checkout writer-a + commit id: "Delete rows 100-199" tag: "read_version=2" + checkout writer-b + commit id: "Delete rows 500-599" tag: "read_version=2" + checkout main + merge writer-a tag: "v3" + checkout writer-b + commit id: "Rebase: merge deletion vectors" type: HIGHLIGHT + checkout main + merge writer-b tag: "v4" +``` + +In this scenario: + +- Writer A deletes rows 100-199 and successfully commits version 3 +- Writer B attempts to commit but detects version 3 exists +- Writer B's transaction is rebasable because it only modified deletion vectors (not data files) and `affected_rows` do not overlap +- Writer B rebases by merging Writer A's deletion vector with its own, write it to storage +- Writer B successfully commits version 4 + +#### Retryable Conflict Example + +The following diagram illustrates a retryable conflict where an Update operation encounters a concurrent Rewrite (compaction) that prevents automatic rebasing: + +```mermaid +gitGraph + commit id: "v1" + commit id: "v2" + branch writer-a + branch writer-b + checkout writer-a + commit id: "Compact fragments 1-5" tag: "read_version=2" + checkout writer-b + commit id: "Update rows in fragment 3" tag: "read_version=2" + checkout main + merge writer-a tag: "v3: fragments compacted" + checkout writer-b + commit id: "Detect conflict: cannot rebase" type: REVERSE +``` + +In this scenario: + +- Writer A compacts fragments 1-5 into a single fragment and successfully commits version 3 +- Writer B attempts to update rows in fragment 3 but detects version 3 exists +- Writer B's Update transaction is retryable but not rebasable: fragment 3 no longer exists after compaction +- The commit layer returns a retryable conflict error +- The application must re-execute the Update operation against version 3, locating the rows in the new compacted fragment + +#### Incompatible Conflict Example + +The following diagram illustrates an incompatible conflict where a Delete operation encounters a concurrent Restore that fundamentally invalidates the operation: + +```mermaid +gitGraph + commit id: "v1" + commit id: "v2" + commit id: "v3" + branch writer-a + branch writer-b + checkout writer-a + commit id: "Restore to v1" tag: "read_version=3" + checkout writer-b + commit id: "Delete rows added in v2-v3" tag: "read_version=3" + checkout main + merge writer-a tag: "v4: restored to v1" + checkout writer-b + commit id: "Detect conflict: incompatible" type: REVERSE +``` + +In this scenario: + +- Writer A restores the table to version 1 and successfully commits version 4 +- Writer B attempts to delete rows that were added between versions 2 and 3 +- Writer B's Delete transaction is incompatible: the table has been restored to version 1, and the rows it intended to delete no longer exist +- The commit fails with a non-retryable error +- If the caller retries the deletion operation against version 4, it would either delete nothing (if those rows don't exist in v1) or delete different rows (if similar row IDs exist in v1), producing semantically different results than originally intended + +## External Manifest Store + +If the backing object store does not support atomic operations (rename-if-not-exists or put-if-not-exists), an external manifest store can be used to enable concurrent writers. + +An external manifest store is a key-value store that supports put-if-not-exists operations. +The external manifest store supplements but does not replace the manifests in object storage. +A reader unaware of the external manifest store can still read the table, but may observe a version up to one commit behind the true latest version. + +### Commit Process with External Store + +The commit process follows a four-step protocol: + +![External Store Commit Process](../../images/external_store_commit.gif) + +1. **Stage manifest**: `PUT_OBJECT_STORE {dataset}/_versions/{version}.manifest-{uuid}` + - Write the new manifest to object storage under a unique path determined by a new UUID + - This staged manifest is not yet visible to readers + +2. **Commit to external store**: `PUT_EXTERNAL_STORE base_uri, version, {dataset}/_versions/{version}.manifest-{uuid}` + - Atomically commit the path of the staged manifest to the external store using put-if-not-exists + - The commit is effectively complete after this step + - If this operation fails due to conflict, another writer has committed this version + +3. **Finalize in object store**: `COPY_OBJECT_STORE {dataset}/_versions/{version}.manifest-{uuid} → {dataset}/_versions/{version}.manifest` + - Copy the staged manifest to the final path + - This makes the manifest discoverable by readers unaware of the external store + +4. **Update external store pointer**: `PUT_EXTERNAL_STORE base_uri, version, {dataset}/_versions/{version}.manifest` + - Update the external store to point to the finalized manifest path + - Completes the synchronization between external store and object storage + +**Fault Tolerance:** + +If the writer fails after step 2 but before step 4, the external store and object store are temporarily out of sync. +Readers detect this condition and attempt to complete the synchronization. +If synchronization fails, the reader refuses to load to ensure dataset portability. + +### Reader Process with External Store + +The reader follows a validation and synchronization protocol: + +![External Store Reader Process](../../images/external_store_reader.gif) + +1. **Query external store**: `GET_EXTERNAL_STORE base_uri, version` → `path` + - Retrieve the manifest path for the requested version + - If the path does not end with a UUID, return it directly (synchronization complete) + - If the path ends with a UUID, synchronization is required + +2. **Synchronize to object store**: `COPY_OBJECT_STORE {dataset}/_versions/{version}.manifest-{uuid} → {dataset}/_versions/{version}.manifest` + - Attempt to finalize the staged manifest + - This operation is idempotent + +3. **Update external store**: `PUT_EXTERNAL_STORE base_uri, version, {dataset}/_versions/{version}.manifest` + - Update the external store to reflect the finalized path + - Future readers will see the synchronized state + +4. **Return finalized path**: Return `{dataset}/_versions/{version}.manifest` + - Always return the finalized path + - If synchronization fails, return an error to prevent reading inconsistent state + +This protocol ensures that datasets using external manifest stores remain portable: copying the dataset directory preserves all data without requiring the external store. diff --git a/docs/src/format/table/versioning.md b/docs/src/format/table/versioning.md new file mode 100644 index 00000000000..745dd1ccd87 --- /dev/null +++ b/docs/src/format/table/versioning.md @@ -0,0 +1,34 @@ +# Format Versioning + +## Feature Flags + +As the table format evolves, new feature flags are added to the format. +There are two separate fields for checking for feature flags, +depending on whether you are trying to read or write the table. +Readers should check the `reader_feature_flags` to see if there are any flag it is not aware of. +Writers should check `writer_feature_flags`.

When compaction and index building +run concurrently, they often conflict because both need to modify the same indices. This typically +causes the compaction to fail and retry, and repeated failures can cause table layout to degrade +over time. + +The Fragment Reuse Index (FRI) solves this by allowing compaction to skip the index remap step. +Instead of immediately updating indices, compaction records a mapping from old fragment row +addresses to new ones. When indices are loaded into the cache, the FRI is applied to translate +the old row addresses to the current ones. This adds a small cost to index load time but does +not affect query performance once the index is cached. + +This decoupling means compaction and index building no longer conflict, which is especially +valuable for tables that are continuously ingesting data while also maintaining indices. + +To enable the FRI, set `defer_index_remap=True` when compacting: + +```python +dataset.optimize.compact_files(defer_index_remap=True) +``` + +For details on the index format and usage patterns, see the +[Fragment Reuse Index specification](../format/table/index/system/frag_reuse.md). + +## Indexes + +Training and searching indexes can have unique requirements for compute and memory. This section provides some +guidance on what can be expected for different index types. + +### BTree Index + +The BTree index is a two-level structure that provides efficient range queries and sorted access. +It strikes a balance between an expensive memory structure containing all values and an expensive disk +structure that can't be efficiently searched. + +Training a BTree index is done by sorting the column. This is done using an [external sort](https://en.wikipedia.org/wiki/External_sorting) to constrain the total memory usage to a reasonable amount. Updating a BTree index does not +require re-sorting the entire column. The new values are sorted and the existing values are merged into the new sorted +values in linear time. + +#### Storage Requirements + +The BTree index is essentially a sorted copy of a column. The storage requirements are therefore the same as the column +but an additional 4 bytes per value is required to store the row ID and there is a small lookup structure which +should be roughly 0.001% of the size of the column. + +#### Memory Requirements + +Training a BTree index requires some RAM but the current implementation spills to disk rather aggressively and so the +total memory usage is fairly low. + +When searching a BTree index, the index is loaded into the index cache in pages. Each page contains 4096 values. + +#### Performance + +The sort stage is the most expensive step in training a BTree index. The time complexity is O(n log n) where n is the number of rows in the column. At very large scales this can be a bottleneck and a distributed sort may be necessary. Lance currently does +not have anything builtin for this but work is underway to add this functionality. Training an index in parts as the data grows +may be slightly more efficient than training the entire index at once if you have the flexibility to do so. + +When the BTree index is fully loaded into the index cache, the search time scales linearly with the number of rows that match the +query. When the BTree index is not fully loaded into the index cache, the search time will be controlled by the number of pages +that need to be loaded from disk and the speed of storage. The parts_loaded metric in the execution metrics can tell you how many +pages were loaded from disk to satisfy a query. + +### Bitmap Index + +The Bitmap index is an inverted lookup table that stores a bitmap for each possible value in the column. These bitmaps are compressed and serialized as a [Roaring Bitmap](https://roaringbitmap.org/). + +A bitmap index is currently trained by accumulating the column into a hash map from value to a vector of row ids. Each value +is then serialized into a bitmap and stored in a file. + +### Storage Requirements + +The size of a bitmap index is difficult to calculate precisely but will generally scale with the number of unique values in the +column since a unique bitmap is required for each value and a single bitmap with all rows will compress more efficiently than +many bitmaps with a small number of rows. + +#### Memory Requirements + +Since training a bitmap index requires collecting the values into a hash map you will need at least 8 bytes of memory per row. +In addition, if you have many unique values, then you will need additional memory for the keys of the hash map. Training large +bitmaps with many unique values at scale can be memory intensive. + +When a bitmap index is searched, bitmaps are loaded into the session cache individually. The size of the bitmap will depend on +the number of rows that match the token. + +### Performance + +When the bitmap index is fully loaded into the index cache, the search time scales linearly with the number of values that the +query requires. This makes the bitmap very fast for equality queries or very small ranges. Queries against large ranges are +currently extremely slow and the btree index is much faster for large range queries. + +When a bitmap index is not fully loaded into the index cache, the search time will be controlled by the number of bitmaps that +need to be loaded from disk and the speed of storage. The parts_loaded metric in the execution metrics can tell you how many +bitmaps were loaded from disk to satisfy a query. + +### Vector Index + +Vector indexes (IVF_PQ, IVF_HNSW_SQ, etc.) are built in multiple phases, each with different memory requirements. + +#### IVF Training + +The IVF (Inverted File) phase clusters vectors into partitions using KMeans. To train the KMeans model, a sample of the +dataset is loaded into memory. The size of this sample is determined by: + +``` +training_data = num_partitions * sample_rate * dimension * sizeof(data_type) +``` + +The default `sample_rate` is 256. For example, with 1024 partitions, 768-dimensional float32 vectors, and the default +sample rate: + +``` +1024 * 256 * 768 * 4 bytes = 768 MiB +``` + +In addition to the training data, each KMeans iteration allocates membership and distance vectors proportional to the +number of training vectors (8 bytes per vector). The centroids themselves require `num_partitions * dimension * +sizeof(data_type)` bytes. In practice, the training data dominates and these additional allocations are small in +comparison. + +If the dataset has fewer rows than `num_partitions * sample_rate`, the entire dataset is used for training instead. + +#### Quantizer Training + +After IVF training, a quantizer (e.g. PQ, SQ) is trained to compress vectors. This phase may sample some of the +dataset, but the sample size is tied to properties of the quantizer and the vector dimension rather than the size of the +dataset. As a result, quantizer training typically requires very little RAM compared to the IVF phase. + +#### Shuffling + +The final phase scans the entire vector column, transforms each vector (assigning it to an IVF partition and quantizing +it), and writes the results into per-partition files on disk. This is a streaming operation — data is not accumulated in +memory. + +The input scan uses a 2 GiB I/O readahead buffer by default (configurable via `LANCE_DEFAULT_IO_BUFFER_SIZE`) and reads +batches of 8,192 rows. Incoming batches are transformed in parallel, with `num_cpus - 2` batches in flight at a time +(configurable via `LANCE_CPU_THREADS`). Each batch is sorted by partition ID and the slices are written directly to the +corresponding partition file. The in-flight memory during this phase is roughly: + +``` +io_readahead_buffer + num_cpu_threads * batch_size * (raw_vector_size + transformed_vector_size) +``` + +Each partition has an open file writer with roughly 8 MiB of accumulation buffer. In practice there shouldn't be that +much data accumulated in a single partition anyways. Instead, the max accumulation will be roughly the final size of +the partitions which comes out to `num_rows * (num_sub_vectors + 8) bytes`. For example, 100M rows with a 1536-dimensional +vector will have 96 sub-vectors and so the max accumulation will be ~10GB. The additional 8 bytes per row is for the row ID. + +#### Storage Requirements + +The on-disk size of a vector index consists of the IVF centroids and the quantized vectors. + +The centroids require: + +``` +num_partitions * dimension * sizeof(data_type) +``` + +This is typically small. For example, 10K partitions with 768-dimensional float32 vectors is only 30 MiB. + +The quantized vectors make up the bulk of the index. Each row stores a quantized code plus an 8-byte row ID. The +exact size depends on the quantizer: + +**PQ (Product Quantization):** Each sub-vector is quantized to a single byte, so each row requires +`num_sub_vectors + 8` bytes. For example, 100M rows with 96 sub-vectors: + +``` +100M * (96 + 8) = ~9.7 GiB +``` + +**SQ (Scalar Quantization):** Each dimension is independently quantized to a single byte, so each row requires +`dimension + 8` bytes. SQ preserves more information than PQ but requires more storage. For example, 100M rows with +768-dimensional vectors: + +``` +100M * (768 + 8) = ~72.3 GiB +``` + +**RQ (RaBitQ):** Vectors are quantized to binary codes with a configurable number of bits per +dimension. Each row also stores per-row scale and offset factors (4 bytes each) used for distance correction. Each +row requires `dimension * num_bits / 8 + 16` bytes (8 bytes for the row ID plus 8 bytes for the factors). For +example, 100M rows with 768 dimensions and 1 bit per dimension: + +``` +100M * (768 * 1 / 8 + 16) = ~10.8 GiB +``` diff --git a/docs/src/guide/read_and_write.md b/docs/src/guide/read_and_write.md index cbfb65a1e4c..ec6cde5173a 100644 --- a/docs/src/guide/read_and_write.md +++ b/docs/src/guide/read_and_write.md @@ -19,6 +19,8 @@ also supports `Iterator` of `pyarrow.RecordBatch` es.

For simple term searches, disabling this option can save considerable storage space without impacting performance. + +- Keep `lower_case=True` enabled for most applications to ensure case-insensitive search behavior. This provides a better user experience and matches common search expectations, though you can disable it if case sensitivity is important for your use case. + +- Enable stemming (`stem=True`) when you want better recall by matching word variations (e.g., "running" matches "run"). Disable stemming if you need exact term matching or if your domain requires precise terminology. + +- Consider enabling `remove_stop_words=True` for cleaner search results, especially in content-heavy applications. This removes common words like "the", "and", and "is" from the index, reducing noise and improving relevance. Keep stop words if they carry important meaning in your domain. + +### Query Optimization + +Using specific, targeted search terms often yields better performance than broad, generic queries. More specific terms reduce the number of potential matches and allow the index to work more efficiently. Consider analyzing your most common search patterns and optimizing your index configuration accordingly. + +Combining full-text search with metadata filters can significantly reduce the search space and improve performance. Use structured data filters to narrow down results before applying text search, or vice versa. This approach is particularly effective for large datasets where you can eliminate many irrelevant documents early in the query process. + +### Further Reading + +For advanced usage instructions with different tokenizers and more technical details on the index training process, including information about the expected memory and disk usage, visit the [full-text index](../format/table/index/scalar/fts.md) specification. + +## Next Steps + +Check out the **[User Guide](../guide/read_and_write.md)** and explore the Lance API in more detail. diff --git a/docs/src/quickstart/index.md b/docs/src/quickstart/index.md index 864972ccc6b..00daa6a4ee4 100644 --- a/docs/src/quickstart/index.md +++ b/docs/src/quickstart/index.md @@ -20,7 +20,7 @@ pip install pylance For the latest features and bug fixes, you can install the preview version: ```bash -pip install --pre --extra-index-url https://pypi.fury.io/lancedb/pylance +pip install --pre --extra-index-url https://pypi.fury.io/lance-format/pylance ``` > Note: Preview releases receive the same level of testing as regular releases. diff --git a/docs/src/quickstart/vector-search.md b/docs/src/quickstart/vector-search.md index e157c193486..6b1f6a5e516 100644 --- a/docs/src/quickstart/vector-search.md +++ b/docs/src/quickstart/vector-search.md @@ -280,4 +280,4 @@ print(result.to_pandas()) ## Next Steps -You should check out **[Versioning Your Datasets with Lance](../quickstart/versioning.md)**.

To the greatest extent permitted by, but not in contravention +of, applicable law, Affirmer hereby overtly, fully, permanently, +irrevocably and unconditionally waives, abandons, and surrenders all of +Affirmer's Copyright and Related Rights and associated claims and causes +of action, whether now known or unknown (including existing as well as +future claims and causes of action), in the Work (i) in all territories +worldwide, (ii) for the maximum duration provided by applicable law or +treaty (including future time extensions), (iii) in any current or future +medium and for any number of copies, and (iv) for any purpose whatsoever, +including without limitation commercial, advertising or promotional +purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each +member of the public at large and to the detriment of Affirmer's heirs and +successors, fully intending that such Waiver shall not be subject to +revocation, rescission, cancellation, termination, or any other legal or +equitable action to disrupt the quiet enjoyment of the Work by the public +as contemplated by Affirmer's express Statement of Purpose. + +3. Public License Fallback. Should any part of the Waiver for any reason +be judged legally invalid or ineffective under applicable law, then the +Waiver shall be preserved to the maximum extent permitted taking into +account Affirmer's express Statement of Purpose. In addition, to the +extent the Waiver is so judged Affirmer hereby grants to each affected +person a royalty-free, non transferable, non sublicensable, non exclusive, +irrevocable and unconditional license to exercise Affirmer's Copyright and +Related Rights in the Work (i) in all territories worldwide, (ii) for the +maximum duration provided by applicable law or treaty (including future +time extensions), (iii) in any current or future medium and for any number +of copies, and (iv) for any purpose whatsoever, including without +limitation commercial, advertising or promotional purposes (the +"License"). The License shall be deemed effective as of the date CC0 was +applied by Affirmer to the Work. Should any part of the License for any +reason be judged legally invalid or ineffective under applicable law, such +partial invalidity or ineffectiveness shall not invalidate the remainder +of the License, and in such case Affirmer hereby affirms that he or she +will not (i) exercise any of his or her remaining Copyright and Related +Rights in the Work or (ii) assert any associated claims and causes of +action with respect to the Work, in either case contrary to Affirmer's +express Statement of Purpose. + +4. Limitations and Disclaimers. + + a. No trademark or patent rights held by Affirmer are waived, abandoned, + surrendered, licensed or otherwise affected by this document. + b. Affirmer offers the Work as-is and makes no representations or + warranties of any kind concerning the Work, express, implied, + statutory or otherwise, including without limitation warranties of + title, merchantability, fitness for a particular purpose, non + infringement, or the absence of latent or other defects, accuracy, or + the present or absence of errors, whether or not discoverable, all to + the greatest extent permissible under applicable law. + c. Affirmer disclaims responsibility for clearing rights of other persons + that may apply to the Work or any use thereof, including without + limitation any person's Copyright and Related Rights in the Work. + Further, Affirmer disclaims responsibility for obtaining any necessary + consents, permissions or other rights required for any use of the + Work. + d.

"Secondary License" + means either the GNU General Public License, Version 2.0, the GNU + Lesser General Public License, Version 2.1, the GNU Affero General + Public License, Version 3.0, or any later versions of those + licenses. + +1.13.

License Grants and Conditions +-------------------------------- + +2.1. Grants + +Each Contributor hereby grants You a world-wide, royalty-free, +non-exclusive license: + +(a) under intellectual property rights (other than patent or trademark) + Licensable by such Contributor to use, reproduce, make available, + modify, display, perform, distribute, and otherwise exploit its + Contributions, either on an unmodified basis, with Modifications, or + as part of a Larger Work; and + +(b) under Patent Claims of such Contributor to make, use, sell, offer + for sale, have made, import, and otherwise transfer either its + Contributions or its Contributor Version. + +2.2. Effective Date + +The licenses granted in Section 2.1 with respect to any Contribution +become effective for each Contribution on the date the Contributor first +distributes such Contribution. + +2.3. Limitations on Grant Scope + +The licenses granted in this Section 2 are the only rights granted under +this License. No additional rights or licenses will be implied from the +distribution or licensing of Covered Software under this License. +Notwithstanding Section 2.1(b) above, no patent license is granted by a +Contributor: + +(a) for any code that a Contributor has removed from Covered Software; + or + +(b) for infringements caused by: (i) Your and any other third party's + modifications of Covered Software, or (ii) the combination of its + Contributions with other software (except as part of its Contributor + Version); or + +(c) under Patent Claims infringed by Covered Software in the absence of + its Contributions. + +This License does not grant any rights in the trademarks, service marks, +or logos of any Contributor (except as may be necessary to comply with +the notice requirements in Section 3.4). + +2.4. Subsequent Licenses + +No Contributor makes additional grants as a result of Your choice to +distribute the Covered Software under a subsequent version of this +License (see Section 10.2) or under the terms of a Secondary License (if +permitted under the terms of Section 3.3). + +2.5. Representation + +Each Contributor represents that the Contributor believes its +Contributions are its original creation(s) or it has sufficient rights +to grant the rights to its Contributions conveyed by this License. + +2.6. Fair Use + +This License is not intended to limit any rights You have under +applicable copyright doctrines of fair use, fair dealing, or other +equivalents. + +2.7. Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6. Disclaimer of Warranty * +* ------------------------- * +* * +* Covered Software is provided under this License on an "as is" * +* basis, without warranty of any kind, either expressed, implied, or * +* statutory, including, without limitation, warranties that the * +* Covered Software is free of defects, merchantable, fit for a * +* particular purpose or non-infringing. The entire risk as to the * +* quality and performance of the Covered Software is with You. * +* Should any Covered Software prove defective in any respect, You * +* (not any Contributor) assume the cost of any necessary servicing, * +* repair, or correction. This disclaimer of warranty constitutes an * +* essential part of this License. No use of any Covered Software is * +* authorized under this License except under this disclaimer. * +* * +************************************************************************ + +************************************************************************ +* * +* 7. Limitation of Liability * +* -------------------------- * +* * +* Under no circumstances and under no legal theory, whether tort * +* (including negligence), contract, or otherwise, shall any * +* Contributor, or anyone who distributes Covered Software as * +* permitted above, be liable to You for any direct, indirect, * +* special, incidental, or consequential damages of any character * +* including, without limitation, damages for lost profits, loss of * +* goodwill, work stoppage, computer failure or malfunction, or any * +* and all other commercial damages or losses, even if such party * +* shall have been informed of the possibility of such damages. This * +* limitation of liability shall not apply to liability for death or * +* personal injury resulting from such party's negligence to the * +* extent applicable law prohibits such limitation. Some * +* jurisdictions do not allow the exclusion or limitation of * +* incidental or consequential damages, so this exclusion and * +* limitation may not apply to You. * +* * +************************************************************************ + +8. Litigation +------------- + +Any litigation relating to this License may be brought only in the +courts of a jurisdiction where the defendant maintains its principal +place of business and such litigation shall be governed by laws of that +jurisdiction, without reference to its conflict-of-law provisions. +Nothing in this Section shall prevent a party's ability to bring +cross-claims or counter-claims. + +9. Miscellaneous +---------------- + +This License represents the complete agreement concerning the subject +matter hereof. If any provision of this License is held to be +unenforceable, such provision shall be reformed only to the extent +necessary to make it enforceable. Any law or regulation which provides +that the language of a contract shall be construed against the drafter +shall not be used to construe this License against a Contributor. + +10. Versions of the License +--------------------------- + +10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section +10.3, no one other than the license steward has the right to modify or +publish new versions of this License. Each version will be given a +distinguishing version number. + +10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version +of the License under which You originally received the Covered Software, +or under the terms of any subsequent version published by the license +steward. + +10.3. Modified Versions + +If you create software not governed by this License, and you want to +create a new license for such software, you may create and use a +modified version of this License if you rename the license and remove +any references to the name of the license steward (except to note that +such modified license differs from this License). + +10.4. Distributing Source Code Form that is Incompatible With Secondary +Licenses + +If You choose to distribute Source Code Form that is Incompatible With +Secondary Licenses under the terms of this version of the License, the +notice described in Exhibit B of this License must be attached. + +Exhibit A - Source Code Form License Notice +------------------------------------------- + + This Source Code Form is subject to the terms of the Mozilla Public + License, v. 2.0.

Copyright and Related Rights. A Work made available under CC0 may be +protected by copyright and related or neighboring rights ("Copyright and +Related Rights"). Copyright and Related Rights include, but are not +limited to, the following: + + i. the right to reproduce, adapt, distribute, perform, display, + communicate, and translate a Work; + ii. moral rights retained by the original author(s) and/or performer(s); +iii. publicity and privacy rights pertaining to a person's image or + likeness depicted in a Work; + iv. rights protecting against unfair competition in regards to a Work, + subject to the limitations in paragraph 4(a), below; + v. rights protecting the extraction, dissemination, use and reuse of data + in a Work; + vi. database rights (such as those arising under Directive 96/9/EC of the + European Parliament and of the Council of 11 March 1996 on the legal + protection of databases, and under any national implementation + thereof, including any amended or successor version of such + directive); and +vii. other similar, equivalent or corresponding rights throughout the + world based on applicable law or treaty, and any national + implementations thereof. + +2. Waiver.

Affirmer makes the Waiver for the benefit of each +member of the public at large and to the detriment of Affirmer's heirs and +successors, fully intending that such Waiver shall not be subject to +revocation, rescission, cancellation, termination, or any other legal or +equitable action to disrupt the quiet enjoyment of the Work by the public +as contemplated by Affirmer's express Statement of Purpose. + +3.

Effective Date + +The licenses granted in Section 2.1 with respect to any Contribution +become effective for each Contribution on the date the Contributor first +distributes such Contribution. + +2.3. Limitations on Grant Scope + +The licenses granted in this Section 2 are the only rights granted under +this License. No additional rights or licenses will be implied from the +distribution or licensing of Covered Software under this License. +Notwithstanding Section 2.1(b) above, no patent license is granted by a +Contributor: + +(a) for any code that a Contributor has removed from Covered Software; + or + +(b) for infringements caused by: (i) Your and any other third party's + modifications of Covered Software, or (ii) the combination of its + Contributions with other software (except as part of its Contributor + Version); or + +(c) under Patent Claims infringed by Covered Software in the absence of + its Contributions. + +This License does not grant any rights in the trademarks, service marks, +or logos of any Contributor (except as may be necessary to comply with +the notice requirements in Section 3.4). + +2.4.

Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6.

Always include descriptive messages. +- Don't silently guard against impossible conditions — use `debug_assert!`, return an explicit error, or remove the check. +- Log warnings on best-effort/cleanup failures instead of silently swallowing or propagating errors. +- Log warnings for silent no-ops (skipped operations); omit warnings before errors since the error message is sufficient. +- Avoid `unwrap_or(default)` on map lookups for required config params — use `.ok_or_else(|| Error::...)` and verify key names match between serialization and deserialization. +- Advance all parallel iterators before any `continue` branches — early exits that skip `.next()` calls cause misalignment. +- Bind `iter.next()` with `let Some(x) = iter.next() else { ... }` — never call `.next()` twice to check-then-use. + +## Naming + +- Reserve `_`-prefixed names for truly unused bindings — if a variable is read, drop the underscore. +- Prefix boolean variables with `is_` or `has_` instead of ambiguous `with_` or bare adjectives. +- Name booleans so `false` (zero/`Default::default()`) is the desired default — use `disable_*` instead of `enable_*` when the feature should be on by default. +- Name functions to match their actual scope — e.g., `handle_partition_system_columns` not `handle_system_columns` if only a subset is handled. + +## Testing + +- Use `record_batch!()` from `arrow_array` to construct `RecordBatch` in tests instead of manual Schema/Arc/try_new boilerplate. +- Use `gen_batch()` builder API (`.col()`, `.into_reader_rows()`) for test data setup instead of manual Arrow construction. +- Use `.try_into_batch()` instead of `.try_into_stream().try_collect()` for scanner results in tests. +- Use plain `"memory://"` URIs in tests — no atomic counters or unique suffixes needed. +- Assert on both error variant (`assert!(matches!(error, ErrorType::Variant { .. }))`) and message content — don't just check `is_err()`. + +## Documentation + +- Add doc comments to public API elements that convey semantic meaning, valid values, and effects — don't restate type signatures. +- Document enum variant doc comments with behavioral semantics, not just labels. For numeric parameters, state whether it's an id, count, index, etc. +- Add doc comments to magic constants, thresholds, and non-obvious transformation functions — explain what the value represents and why it was chosen. +- Comment fallback/guard code paths with when they trigger and why they exist. +- Ensure doc comments match actual semantics — distinguish mutates-in-place (`&mut self`) from returns-new-value. +- Use explicit forward-looking language (`TODO`, `FIXME`) in comments to distinguish current behavior from planned changes. +- Document the semantic meaning of both present and absent states for `Option<T>` fields. +- Use precise domain terminology — avoid ambiguous abbreviations (e.g., "FIXED" vs "fixed-width") or incorrect terms (e.g., "fields" when meaning "fragments"). + +## lance-encoding + +Performance-critical encoding/decoding paths have additional requirements: + +- Hoist loop-invariant conditionals out of hot loops — branch once outside, then use separate loop bodies or monomorphized variants. +- Pre-allocate single contiguous buffers. Default to `buf.resize(len, 0)` for safe initialization; reserve `Vec::with_capacity` + `unsafe { set_len() }` for measured hot paths only, with a `// SAFETY:` comment explaining why the buffer will be fully initialized before read (e.g., immediately followed by `read_exact`). +- Use `spawn_cpu()` only at the async-to-CPU boundary (e.g., FSST, decompression, batch materialization) — never nest redundant `spawn_cpu()` calls. +- Use `expect_next()` and similar utility methods instead of inlining `None`-checks with error returns. diff --git a/docs/src/community/contributing/rust.md b/rust/CONTRIBUTING.md similarity index 70% rename from docs/src/community/contributing/rust.md rename to rust/CONTRIBUTING.md index e7982f33e62..31898b3be1b 100644 --- a/docs/src/community/contributing/rust.md +++ b/rust/CONTRIBUTING.md @@ -32,3 +32,10 @@ If you're working on a performance related feature, benchmarks can be run via: ```bash cargo bench ``` + +If you want detailed logging and full backtraces, set the following environment variables. +More details can be found [here](../docs/src/guide/performance.md#logging). + +```bash +LANCE_LOG=info RUST_BACKTRACE=FULL <cargo-commands> +``` diff --git a/rust/arrow-scalar/Cargo.toml b/rust/arrow-scalar/Cargo.toml new file mode 100644 index 00000000000..f127e6c0bfa --- /dev/null +++ b/rust/arrow-scalar/Cargo.toml @@ -0,0 +1,31 @@ +[package] +name = "lance-arrow-scalar" +version = "57.0.0" +edition.workspace = true +authors.workspace = true +license.workspace = true +repository.workspace = true +description = "Arrow scalar type with Ord, Hash, and Eq support" +keywords.workspace = true +categories.workspace = true +rust-version.workspace = true +readme = "README.md" + +[dependencies] +# Note: this is a core crate and we should aim to keep this dependency list +# as minimal as possible. +arrow-array = { workspace = true } +arrow-buffer = { workspace = true } +arrow-cast = { workspace = true } +arrow-data = { workspace = true } +arrow-row = { workspace = true } +arrow-schema = { workspace = true } +half = { workspace = true } + +[dev-dependencies] +arrow-ord = { workspace = true } +proptest = { workspace = true } +rstest = { workspace = true } + +[lints] +workspace = true diff --git a/rust/arrow-scalar/README.md b/rust/arrow-scalar/README.md new file mode 100644 index 00000000000..7173a116262 --- /dev/null +++ b/rust/arrow-scalar/README.md @@ -0,0 +1,57 @@ +# lance-arrow-scalar + +A scalar type backed by Apache Arrow arrays with `Ord`, `Hash`, and `Eq` support. + +## Overview + +`ArrowScalar` wraps a single-element Arrow array and provides comparison and hashing operations by leveraging Apache Arrow's `OwnedRow` representation.

GCP credential vending using downscoped OAuth2 tokens. +//! +//! This module provides credential vending for GCP Cloud Storage by obtaining +//! OAuth2 access tokens and downscoping them using Credential Access Boundaries (CAB). +//! +//! ## Authentication +//! +//! This module uses [Application Default Credentials (ADC)][adc] for authentication. +//! ADC automatically finds credentials based on the environment: +//! +//! 1. **`GOOGLE_APPLICATION_CREDENTIALS` environment variable**: Set this to the path +//! of a service account key file (JSON format) before starting the application. +//! 2. **Well-known file locations**: `~/.config/gcloud/application_default_credentials.json` +//! on Linux/macOS, or the equivalent on Windows. +//! 3. **Metadata server**: When running on GCP (Compute Engine, Cloud Run, GKE, etc.), +//! credentials are automatically obtained from the metadata server. +//! +//! For production deployments on GCP, using the metadata server (option 3) is recommended +//! as it doesn't require managing key files. +//! +//! [adc]: https://cloud.google.com/docs/authentication/application-default-credentials +//! +//! ## Service Account Impersonation +//! +//! For multi-tenant scenarios, you can configure `service_account` to impersonate a +//! different service account. The base credentials (from ADC) must have the +//! `roles/iam.serviceAccountTokenCreator` role on the target service account. +//! +//! ## Permission Scoping +//! +//! Permissions are enforced using GCP's Credential Access Boundaries: +//! - **Read**: `roles/storage.legacyObjectReader` + `roles/storage.objectViewer` (read and list) +//! - **Write**: Read permissions + `roles/storage.legacyBucketWriter` + `roles/storage.objectCreator` +//! - **Admin**: Write permissions + `roles/storage.objectAdmin` (includes delete) +//! +//! The downscoped token is restricted to the specific bucket and path prefix. +//! +//! Note: Legacy roles are used because modern roles like `storage.objectCreator` lack +//! `storage.buckets.get` which many client libraries require. + +use std::collections::HashMap; + +use async_trait::async_trait;

It contains a file format, table format, and catalog spec that allows you to build a complete lakehouse on top of object storage to power your AI workflows. -### 1. Reproducibility is a must-have +The key features of Lance include: -Versioning and experimentation support should be built into the dataset instead of requiring multiple tools.<br/> -It should also be efficient and not require expensive copying everytime you want to create a new version.<br/> -We call this "Zero copy versioning" in Lance. It makes versioning data easy without increasing storage costs. +* **Expressive hybrid search:** Combine vector similarity search, full-text search (BM25), and SQL analytics on the same dataset with accelerated secondary indices. -### 2. Cloud storage is now the default +* **Lightning-fast random access:** 100x faster than Parquet or Iceberg for random access without sacrificing scan performance. -Remote object storage is the default now for data science and machine learning and the performance characteristics of cloud are fundamentally different.<br/> -Lance format is optimized to be cloud native. Common operations like filter-then-take can be order of magnitude faster -using Lance than Parquet, especially for ML data. +* **Native multimodal data support:** Store images, videos, audio, text, and embeddings in a single unified format with efficient blob encoding and lazy loading. -### 3. Vectors must be a first class citizen, not a separate thing +* **Data evolution:** Efficiently add columns with backfilled values without full table rewrites, perfect for ML feature engineering. -The majority of reasonable scale workflows should not require the added complexity and cost of a -specialized database just to compute vector similarity. Lance integrates optimized vector indices -into a columnar format so no additional infrastructure is required to get low latency top-K similarity search. +* **Zero-copy versioning:** ACID transactions, time travel, and automatic versioning without needing extra infrastructure. -### 4. Open standards is a requirement +* **Rich ecosystem integrations:** Apache Arrow, Pandas, Polars, DuckDB, Apache Spark, Ray, Trino, Apache Flink, and open catalogs (Apache Polaris, Unity Catalog, Apache Gravitino). -The DS/ML ecosystem is incredibly rich and data *must be* easily accessible across different languages, tools, and environments. -Lance makes Apache Arrow integration its primary interface, which means conversions to/from is 2 lines of code, your -code does not need to change after conversion, and nothing is locked-up to force you to pay for vendor compute. -We need open-source not fauxpen-source. +For more details, see the full [Lance format specification](https://lance.org/format). diff --git a/rust/lance/benches/distributed_vector_build.rs b/rust/lance/benches/distributed_vector_build.rs new file mode 100644 index 00000000000..5a9b2d70602 --- /dev/null +++ b/rust/lance/benches/distributed_vector_build.rs @@ -0,0 +1,449 @@ +// SPDX-License-Identifier: Apache-2.0 +// SPDX-FileCopyrightText: Copyright The Lance Authors + +use std::fs;
