Outlook

The Debezium 1.9 release stream will remain the current long-running version for the next three months. During this time, we will continue to evaluate user reports and do micro-releases to address bugs and regressions depending on severity.

The development on Debezium 2.0 is moving along quite nicely. We have entered the second half of the development cycle, and we’ll begin beta releases with the next release toward the end of July.

Stay tuned for more in the coming weeks, stay cool out there, and happy capturing!

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.
