I’m thrilled to announce the release of Debezium 1.5.0.Final!

With Debezium 1.5, the LogMiner-based CDC implementation for Oracle moves from Incubating to Stable state, and there’s a brand-new implementation of the MySQL connector, which brings features like transaction metadata support. Other key features include support for a new "signalling table", which for instance can be used to implement schema changes with the Oracle connector, and support for TRUNCATE events with Postgres. There’s also many improvements to the community-led connectors for Vitess and Apache Cassandra, as well as wide range of bug fixes and other smaller improvements.

It’s my pleasure to announce the release of Debezium 1.5.0.CR1!

As we begin moving toward finalizing the Debezium 1.5 release stream, the Oracle connector has been promoted to stable and there were some TLS improvements for the Cassandra connector, as well as numerous bugfixes. Overall, 50 issues have been addressed for this release.

We are very happy to announce the release of Debezium 1.5.0.Beta2!

About three months after the 1.0 release, this new version comes with many exciting new features such as:

It’s my pleasure to announce the release of Debezium 1.1.0.CR1!

This release brings a brand-new API module, including a facility for overriding the schema and value conversion of specific columns. The Postgres connector gained the ability to reconnect to the database after a connection loss, and the MongoDB connector supports the metrics known from other connectors now.

We have developed a Debezium connector for usage with Db2 which is now available as part of the Debezium incubator. Here we describe the use case we have for Change Data Capture (CDC), the various approaches that already exist in the Db2 ecology, and how we came to Debezium. In addition, we motivate the approach we took to implementing the Db2 Debezium connector.

Release early, release often! After the 1.1 Beta1 and 1.0.1 Final releases earlier this week, I’m today happy to share the news about the release of Debezium 1.1.0.Beta2!

The main addition in Beta2 is support for integration tests of your change data capture (CDC) set-up using Testcontainers. In addition, the Quarkus extension for implementing the outbox pattern as well as the SMT for extracting the after state of change events have been re-worked and offer more configuration flexibility now.

It’s my pleasure to announce the release of Debezium 1.1.0.Beta1!

This release adds support for transaction marker events, an incubating connector for the IBM Db2 database as well as a wide range of bug fixes. As the 1.1 release still is under active development, we’ve backported an asorted set of bug fixes to the 1.0 branch and released Debezium 1.0.1.Final, too.

At the time of writing this, not all connector archives have been synched to Maven Central yet; this should be the case within the next few others.
