Debezium 0.8.2 Released

The Debezium team is back from summer holidays and we’re happy to announce the release of Debezium 0.8.2!

This is a bugfix release to the current stable release line of Debezium, 0.8.x, while the work on Debezium 0.9 is continuing.

Note: By accident the version of the release artifacts is 0.8.2 instead of 0.8.2.Final. This is not in line with our recently established convention of always letting release versions end with qualifiers such as Alpha1, Beta1, CR1 or Final. The next version in the 0.8 line will be 0.8.3.Final and we’ll improve our release pipeline to make sure that this situation doesn’t occur again.

The 0.8.2 release contains 10 fixes overall, most of them dealing with issues related to DDL parsing as done by the Debezium MySQL connector. For instance, implicit non-nullable primary key columns will be handled correctly now using the new Antlr-based DDL parser (DBZ-860). Also the MongoDB connector saw a bug fix (DBZ-838): initial snapshots will be interrupted now if the connector is requested to stop (e.g. when shutting down Kafka Connect). More a useful improvement rather than a bug fix is the Postgres connector’s capability to add the table, schema and database names to the source block of emitted CDC events (DBZ-866).

Thanks a lot to community members Andrey Pustovetov, Cliff Wheadon and Ori Popowski for their contributions to this release!

What’s next?

We’re continuing the work on Debezium 0.9, which will mostly be about improvements to the SQL Server and Oracle connectors. Both will get support for handling structural changes to captured tables while the connectors are running. Also the exploration of alternatives to using the XStream API for the Oracle connector continues.

Finally, a recurring theme of our work is to further consolidate the code bases of the different connectors, which will allow us to roll out new and improved features more quickly across all the Debezium connectors. The recently added Oracle and SQL Server connectors already share a lot of code, and in the next step we’ve planned to move the existing Postgres connector to the new basis established for these two connectors.

If you’d like to learn more about some middle and long term ideas, please check out our roadmap. Also please get in touch with us if you got any ideas or suggestions for future development.

About Debezium

Debezium is an open source distributed platform that turns your existing databases into event streams, so applications can see and respond almost instantly to each committed row-level change in the databases. Debezium is built on top of Kafka and provides Kafka Connect compatible connectors that monitor specific database management systems. Debezium records the history of data changes in Kafka logs, so your application can be stopped and restarted at any time and can easily consume all of the events it missed while it was not running, ensuring that all events are processed correctly and completely. Debezium is open source under the Apache License, Version 2.0.
