This class organizes data in a hierarchical structure + * using Arrow's {@link VectorSchemaRoot} and {@link FieldVector} to represent columns and nested structures. + * The serialization process follows a strict column-ordering scheme, where fields are named based on their ordinal + * position in the serialization order, ensuring deterministic and consistent data layout for both writing and reading. + * + *

Serialization and Deserialization Specification:

+ *
    + *
  1. Primitive Types: + * Primitive types (byte, int, long, boolean, float, double, string, and byte arrays) are serialized as individual + * columns under the current root path in the {@link VectorSchemaRoot}. Each column is named using the format + * {currentPath}.{ordinal}, where ordinal represents the order in which the primitive is + * written, starting from 0. For example, if the current root path is "root" and three primitives are + * written, their column names will be "root.0", "root.1", and "root.2". + * The order of serialization is critical, as it determines the column names and must match during deserialization. + * Each column is represented by an appropriate Arrow vector type (e.g., {@link TinyIntVector} for byte, + * {@link VarCharVector} for string, etc.), with values appended at the current row index of the root path. + *
    2. + *
  2. NamedWriteable Types: + * {@link NamedWriteable} objects are treated as nested structures and serialized as a single column of type + * {@link StructVector} under the current root path. The column is named {currentPath}.{ordinal}, + * where ordinal is the next available column index. For example, if the current root path is + * "root" and the current column ordinal is 3, the struct column will be named "root.3". + * The struct's fields are serialized under a nested path derived from the column name (e.g., "root.3"), + * with subfields named "root.3.0", "root.3.1", etc., based on their serialization order. + * The struct's metadata includes the name key, set to the {@link NamedWriteable#getWriteableName()} + * value, which is used during deserialization to identify the appropriate {@link Writeable.Reader}. + * The row index of the nested path inherits the parent path's row index to maintain structural consistency. + *
    3. + *
  3. List Types: + * Lists of {@link Writeable} objects are serialized as a single column of type {@link StructVector} under the + * current root path, named {currentPath}.{ordinal}, where ordinal is the next available + * column index. For example, if the current root path is "root" and the current ordinal is 4, the + * list's struct column will be named "root.4". The elements of the list are serialized under a nested + * path (e.g., "root.4"), with each element's fields named "root.4.0", + * "root.4.1", etc., based on their serialization order within the element. Each element is written + * at a new row index, starting from the parent path's row index, and a boolean flag is written after each element + * to indicate whether more elements follow (true for all but the last element, false + * for the last). All elements in the list must have the same type and structure to ensure consistent column layout + * across rows; otherwise, deserialization may fail due to mismatched schemas. + *.
      + *
    • List of Lists: + * A list of lists (e.g., List<List<T>>, where T is a {@link Writeable}) + * is serialized as a nested {@link StructVector} within the outer list's struct column. For example, if the + * outer list is serialized under "root.4", each inner list is treated as a {@link Writeable} + * element and serialized as a nested {@link StructVector} column under the path "root.4". If + * the inner list is the first element of the outer list, it occupies column "root.4.0", with + * its fields named "root.4.0.0", "root.4.0.1", etc., based on the serialization + * order of its elements. Each inner list is written at a new row index under the outer list’s nested path, + * starting from the outer list’s row index, and a boolean flag is written after each inner list element to + * indicate continuation within the inner list. The outer list’s boolean flags indicate continuation of inner + * lists. All inner lists must have the same type and structure, and their elements must also be consistent + * in type and structure to ensure a uniform schema across rows. During deserialization, the outer list is + * read as a {@link StructVector}, and each inner list is deserialized as a nested {@link StructVector}, + * with row indices and boolean flags used to determine the boundaries of inner and outer lists. + *
      • + *
    + *
    4. + *
  4. Map Types: + * Maps (key-value pairs are serialized as a single column of type + * {@link StructVector} under the current root path, named {currentPath}.{ordinal}. + * Currently, only empty or null maps are supported, serialized as a null value in the + * struct vector at the current row index. Future implementations may support non-empty maps with key and value + * vectors (e.g., {@link VarCharVector} for keys and a uniform type for values). + *
    5. + *
+ * + *

Usage Notes:

+ *
    + *
  • The order of serialization must match the order of deserialization to ensure correct column alignment, as column + * names are based on ordinals determined by the sequence of write operations.
    • + *
  • All elements in a list must have the same type and structure to maintain a consistent schema across rows. + * Inconsistent structures may lead to deserialization errors due to mismatched column types.
    • + *
  • Ensure that the {@link org.opensearch.core.common.io.stream.NamedWriteableRegistry} provided to {@link ArrowStreamInput} contains readers for all + * {@link NamedWriteable} types serialized by {@link ArrowStreamInput}, using the same + * {@link NamedWriteable#getWriteableName()} value.

This class organizes data in a hierarchical structure - * using Arrow's {@link VectorSchemaRoot} and {@link FieldVector} to represent columns and nested structures. - * The serialization process follows a strict column-ordering scheme, where fields are named based on their ordinal - * position in the serialization order, ensuring deterministic and consistent data layout for both writing and reading. - * - *

Serialization and Deserialization Specification:

- *
    - *
  1. Primitive Types: - * Primitive types (byte, int, long, boolean, float, double, string, and byte arrays) are serialized as individual - * columns under the current root path in the {@link VectorSchemaRoot}. Each column is named using the format - * {currentPath}.{ordinal}, where ordinal represents the order in which the primitive is - * written, starting from 0. For example, if the current root path is "root" and three primitives are - * written, their column names will be "root.0", "root.1", and "root.2". - * The order of serialization is critical, as it determines the column names and must match during deserialization. - * Each column is represented by an appropriate Arrow vector type (e.g., {@link TinyIntVector} for byte, - * {@link VarCharVector} for string, etc.), with values appended at the current row index of the root path. - *
    2. - *
  2. NamedWriteable Types: - * {@link NamedWriteable} objects are treated as nested structures and serialized as a single column of type - * {@link StructVector} under the current root path. The column is named {currentPath}.{ordinal}, - * where ordinal is the next available column index. For example, if the current root path is - * "root" and the current column ordinal is 3, the struct column will be named "root.3". - * The struct's fields are serialized under a nested path derived from the column name (e.g., "root.3"), - * with subfields named "root.3.0", "root.3.1", etc., based on their serialization order. - * The struct's metadata includes the name key, set to the {@link NamedWriteable#getWriteableName()} - * value, which is used during deserialization to identify the appropriate {@link Writeable.Reader}. - * The row index of the nested path inherits the parent path's row index to maintain structural consistency. - *
    3. - *
  3. List Types: - * Lists of {@link Writeable} objects are serialized as a single column of type {@link StructVector} under the - * current root path, named {currentPath}.{ordinal}, where ordinal is the next available - * column index. For example, if the current root path is "root" and the current ordinal is 4, the - * list's struct column will be named "root.4". The elements of the list are serialized under a nested - * path (e.g., "root.4"), with each element's fields named "root.4.0", - * "root.4.1", etc., based on their serialization order within the element. Each element is written - * at a new row index, starting from the parent path's row index, and a boolean flag is written after each element - * to indicate whether more elements follow (true for all but the last element, false - * for the last). All elements in the list must have the same type and structure to ensure consistent column layout - * across rows; otherwise, deserialization may fail due to mismatched schemas. - *.
      - *
    • List of Lists: - * A list of lists (e.g., List<List<T>>, where T is a {@link Writeable}) - * is serialized as a nested {@link StructVector} within the outer list's struct column. For example, if the - * outer list is serialized under "root.4", each inner list is treated as a {@link Writeable} - * element and serialized as a nested {@link StructVector} column under the path "root.4". If - * the inner list is the first element of the outer list, it occupies column "root.4.0", with - * its fields named "root.4.0.0", "root.4.0.1", etc., based on the serialization - * order of its elements. Each inner list is written at a new row index under the outer list’s nested path, - * starting from the outer list’s row index, and a boolean flag is written after each inner list element to - * indicate continuation within the inner list. The outer list’s boolean flags indicate continuation of inner - * lists. All inner lists must have the same type and structure, and their elements must also be consistent - * in type and structure to ensure a uniform schema across rows. During deserialization, the outer list is - * read as a {@link StructVector}, and each inner list is deserialized as a nested {@link StructVector}, - * with row indices and boolean flags used to determine the boundaries of inner and outer lists. - *
      • - *
    - *
    4. - *
  4. Map Types: - * Maps (key-value pairs are serialized as a single column of type - * {@link StructVector} under the current root path, named {currentPath}.{ordinal}. - * Currently, only empty or null maps are supported, serialized as a null value in the - * struct vector at the current row index. Future implementations may support non-empty maps with key and value - * vectors (e.g., {@link VarCharVector} for keys and a uniform type for values). - *

    - *
  • The order of serialization must match the order of deserialization to ensure correct column alignment, as column - * names are based on ordinals determined by the sequence of write operations.
    • - *
  • All elements in a list must have the same type and structure to maintain a consistent schema across rows. - * Inconsistent structures may lead to deserialization errors due to mismatched column types.
    • - *
  • Ensure that the {@link org.opensearch.core.common.io.stream.NamedWriteableRegistry} provided to {@link ArrowStreamInput} contains readers for all - * {@link NamedWriteable} types serialized by {@link ArrowStreamInput}, using the same - * {@link NamedWriteable#getWriteableName()} value.

and `server_thread_utilization_percent` + +### Error Detection + +- **Failed calls**: Monitor non-OK status counts in `status.client` and `status.server` +- **Cancelled operations**: Check `CANCELLED` status counts +- **Resource exhaustion**: Watch for `RESOURCE_EXHAUSTED` status counts + +### Throughput Analysis + +- **Request throughput**: Monitor `client_calls.started` and `server_calls.started` rates +- **Data throughput**: Track `client_calls.request_bytes` and `server_batches.sent_bytes` rates +- **Batch efficiency**: Compare `client_batches.received` with `client_batches.requested` diff

00:00:00 2001 From: bowenlan-amzn Date: Sun, 29 Jun 2025 11:03:54 -0700 Subject: [PATCH 47/77] Streaming Aggregation ## Search Flow Separation - query param 'stream' in rest search action and stored in search request - On coordinator, we uses stream search transport action and search async action uses the new stream callback - On data node, stream transport action pass stream search flag to search context for shard search, aggregation - Reduce context has stream flag from search request ## Coordinator - Sync onPhaseDone for both result consumption callbacks, shard and stream - Result consumer separation between stream and shard ## Data Node - Data node aggregation stream segment aggregation results back, and complete stream by shard result. ## Memory - Optimize memory usage on coordinator - `reduce size = shard_number * ((1.5 * size) + 10)` (needs improve, big accuracy problem) - Remove the unnecessary memory allocation for handling sub aggregation when no sub aggregation exists - Only allocate doc counts per segment in Terms Bucket Aggregator - Remove the priority queue from Terms Bucket Aggregator, return all buckets in build aggregation ## Stream Listener API - Stream search callback - Stream channel listener ## Dev - Enable c2 compiler for local gradlew run - Disable filter optimization ## TODO - Seder at transport currently copy from arrow to native byte
