# Using Debezium to Create ACID Data Lake House | ||
|
||
Do you need to build flexible Data Lakehouse but dont know where to start, do you want your data pipeline to be near realtime and support ACID transactions and updates | ||
its possible using two great projects Debezium and Apache Iceberg without any dependency to kafka or spark | ||
|
||
#### Debezium | ||
Debezium is an open source distributed platform for change data capture. | ||
Debezium extracts realtime database changes as json, avro, protobuf events and delivers to event streaming platforms | ||
(Kafka, Kinesis, Google Pub/Sub, Pulsar are just some of [supported sinks](https://debezium.io/documentation/reference/operations/debezium-server.html#_sink_configuration)), | ||
it provides simple interface to [implement new sink](https://debezium.io/documentation/reference/operations/debezium-server.html#_implementation_of_a_new_sink) | ||
|
||
#### Apache Iceberg | ||
Apache Iceberg is an open table format for huge analytic datasets, with Concurrent ACID writes, it supports Insert and Row level Deletes(Update) [plus many other benefits](https://iceberg.apache.org) | ||
Apache iceberg has great foundation and flexible API which currently supported by Spark, Presto, Trino, Flink and Hive | ||
|
||
## debezium-server-iceberg | ||
|
||
[@TODO visual architecture diagram] | ||
|
||
This project puts both projects together and enables realtime data pipeline to any cloud storage, hdfs destination | ||
with this project its becomes possible to use best features from both projects enjoy realtime structured data feed and ACID table format with update support | ||
|
||
### Extending Debezium Server with Iceberg sink | ||
debezium-server Iceberg sink to [Debezium server quarkus application](https://debezium.io/documentation/reference/operations/debezium-server.html#_installation), | ||
|
||
debezium-server Iceberg sink received realtime json events converted to iceberg rows and processed using iceberg API | ||
received rows are either appended or updated to destination iceberg table as Parquet files, since iceberg supports many cloud storage its easily possible to configure destination which could be | ||
any of hadoop storage cloud storage location. with debezium-server-iceberg its easily possible to replicate your RDBMS to cloud storage | ||
|
||
# update, append | ||
Iceberg consumer by default works with upsert mode. When a row updated on source table destination row replaced with up-to-date record. | ||
with upsert mode data at destination is always deduplicate and kept up to date | ||
|
||
|
||
V 0.12 iceberg | ||
retain deletes as soft delete! | ||
# wait delay batch size | ||
|
||
wait by reading debezium metrics! another great feature of debezium | ||
# destination, iceberg catalog | ||

We love your input! We want to make contributing to this project as easy and transparent as possible, whether it's: | ||
|
||
- Reporting a bug | ||
- Discussing the current state of the code | ||
- Submitting a fix | ||
- Proposing new features | ||
- Becoming a maintainer | ||
|
||
## We Develop with Github | ||
We use github to host code, to track issues and feature requests, as well as accept pull requests. | ||
|
||
## We Use [Github Flow](https://guides.github.com/introduction/flow/index.html), So All Code Changes Happen Through Pull Requests | ||
Pull requests are the best way to propose changes to the codebase. We actively welcome your pull requests: | ||
|
||
1. Fork the repo and create your branch from `master`. | ||
2. If you've added code that should be tested, add tests. | ||
3. If you've changed APIs, update the documentation. | ||
4. Ensure the test suite passes. | ||
5. Make sure your code is formatted. | ||
6. Issue that pull request! | ||
|
||
## Any contributions you make will be under the Apache 2.0 License | ||
In short, when you submit code changes, your submissions are understood to be under the same [Apache-2.0 License](https://github.com/memiiso/debezium-server-iceberg/blob/master/LICENSE) that covers the project. Feel free to contact the maintainers if that's a concern. | ||
|
||
## Report bugs using Github's [issues](https://github.com/memiiso/debezium-server-iceberg/issues) | ||
We use GitHub issues to track public bugs. Report a bug by [opening a new issue](); it's that easy! | ||
|
||
## Write bug reports with detail, background, and sample code | ||
**Good Bug Reports** tend to have: | ||
|
||
- A quick summary and/or background | ||
- Steps to reproduce | ||
- Be specific! | ||
- Give sample code if you can. | ||
- What you expected would happen | ||
- What actually happens | ||
- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work) | ||
