It’s my pleasure to announce the release of Debezium 1.3.0.Beta1!

This release upgrades to the recently released Apache Kafka version 2.6.0, fixes several critical bugs and comes with a renaming of the connector configuration options for selecting the tables to be captured. We’ve also released Debezium 1.2.2.Final, which is a drop-in replacement for all users of earlier 1.2.x releases.

I’m excited to announce the release of Debezium 1.3.0.Alpha1!

This initial pass in the 1.3 release line provides a number of useful new features:

  • A new Debezium Server sink adapter for Azure Event Hubs

  • A new SQL Server connector snapshot mode, initial_only

  • Additional connection timeout options for the MongoDB Connector

Overall, the community fixed not less than 31 issues for this release. Let’s take a closer look at some of them in the remainder of this post.

Hello everyone, my name is René Kerner and I recently joined Red Hat and the Debezium team.

I was working at trivago since 2011, and in 2016 we started using Debezium at version 0.4/0.5 for capturing clickstreams in the offshore datacenters into Kafka and aggregate them in the central cluster. We really intensified Debezium usage within one year and in 2017 we also used it for trivago’s main data.

In 2014 I did my first OSS contributions to Composer, PHP’s dependency management and gave my first talk on it at the Developer Conference (called code.talks for many years now). Then in 2017 I did my first contributions to Debezium with work on the MySQL snapshot process and fixing a MySQL TIME data type issue.

In 2018 I left trivago and started working at Codecentric as a consultant for software architecture and development (mainly JVM focus) and Apache Kafka, doing many trainings and workshops at German "Fortune 500" companies (insurances, industrial sector, media). I was doing lots of networking at that time, where I learned how awesome the community around Kafka is. I was always quite sad I didn’t have more time to focus on OSS projects.

I am happy to announce the release of Debezium 1.2.1.Final!

This release includes several bug fixes to different Debezium connectors, and we highly recommend the upgrade from 1.2.0.Final and earlier versions:

  • The Debezium Postgres connector may have missed events from concurrent transactions when transitioning from snapshotting to streaming events from the WAL (DBZ-2288); this is fixed now when using the exported snapshotting mode; this mode should preferably be used, and for Debezium 1.3 we’re planning for this to be the basis for all the existing snapshotting modes

  • The Postgres JDBC driver got upgraded to 42.2.14 (DBZ-2317), which fixes a CVE in the driver related to processing XML column values sourced from untrusted XML input

  • The Debezium MySQL connector MariaDB’s supports ALTER TABLE statements with IF EXISTS (DBZ-2219); it also handles single dimension DECIMAL columns in CAST expressions (DBZ-2305)

  • The MySQL connector automatically filters out specific DML binlog entries from internal tables when using it with Amazon RDS (DBZ-2275)

  • The Debezium MongoDB connector got more resilient against connection losses (DBZ-2141)

I’m very happy to announce the release of Debezium 1.2.0.Final!

Over the last three months, the community has resolved nearly 200 issues. Key features of this release include:

  • New Kafka Connect single message transforms (SMTs) for content-based event routing and filtering; Upgrade to Apache Kafka 2.5

  • Schema change topics for the Debezium connectors for SQL Server, Db2 and Oracle

  • Support for SMTs and message converters in the Debezium embedded engine

  • Debezium Server, a brand-new runtime which allows to propagate data change events to a range of messaging infrastructures like Amazon Kinesis, Google Cloud Pub/Sub, and Apache Pulsar

  • A new column masking mode "consistent hashing", allowing to anonymize column values while still keeping them correlatable

  • New metrics for the MongoDB connector

  • Improved re-connect capability for the SQL Server connector
