Debezium 0.9.0.Beta1 Released

It’s my pleasure to announce the release of Debezium 0.9.0.Beta1! Oh, and to those of you who are celebrating it — Happy Thanksgiving!

This new Debezium release comes with several great improvements to our work-in-progress SQL Server connector:

  • Initial snapshots can be done using the snapshot isolation level if enabled in the DB (DBZ-941)

  • Changes to the structures of captured tables after the connector has been set up are supported now (DBZ-812)

  • New connector option decimal.handling.mode (DBZ-953) and pass-through of any database.* option to the JDBC driver (DBZ-964)

Besides that, we spent some time on supporting the latest versions of the different databases. The Debezium connectors now support Postgres 11 (DBZ-955) and MongoDB 4.0 (DBZ-974). We are also working on supporting MySQL 8.0, which should be completed in the next 0.9.x release. The Debezium container images have been updated to Kafka 2.0.1 (DBZ-979) and the Kafka Connect image now supports the STATUS_STORAGE_TOPIC environment variable, bringing consistency with CONFIG_STORAGE_TOPIC and OFFSET_STORAGE_TOPIC that already were supported before (DBZ-893).

As usual, several bugs were fixed, too. Several of them dealt with the new Antlr-based DDL parser for the MySQL connector. By now we feel confident about its implementation, so it’s the default DDL parser as of this release (DBZ-757). If you would like to continue to use the legacy parser for some reason, you can do so by setting the ddl.parser.mode connector option to "legacy". This implementation will remain available in the lifetime of Debezium 0.9.x and is scheduled for removal after that. So please make sure to fail issues in JIRA should you run into any problems with the Antlr parser.

Overall, this release contains 21 fixes. Thanks a lot to all the community members who helped with making this happen: Anton Martynov, Deepak Barr, Grzegorz Kołakowski, Olavi Mustanoja, Renato Mefi, Sagar Rao and Shivam Sharma!

What else?

While the work towards Debezium 0.9 continues, we’ve lately been quite busy with presenting Debezium at multiple conferences. You can find the slides and recordings from Kafka Summit San Francisco and Voxxed Days Microservices on our list of online resources around Debezium.

There you also can find the links to the slides of the great talk "The Why’s and How’s of Database Streaming" by Joy Gao of WePay, a Debezium user of the first hour, as well as the link to a blog post by Hans-Peter Grahsl about setting up a CDC pipeline from MySQL into Cosmos DB running on Azure. If you know about other great articles, session recordings or similar on Debezium and change data capture which should be added there, please let us know.

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.
