Debezium 0.5.0 Released


We’re happy to announce that Debezium 0.5.0 is now available for use with Kafka Connect 0.10.2.0. This release also includes a few fixes for the MySQL connector. See the release notes for specifics on these changes, and be sure to check out the Kafka documentation for compatibility with the version of the Kafka broker that you are using.

Kafka Connect 0.10.2.0 comes with a significant new feature called Single Message Transforms, and you can now use them with Debezium connectors. SMTs allow you to modify the messages produced by Debezium connectors and any oher Kafka Connect source connectors, before those messages are written to Kafka. SMTs can also be used with Kafka Connect sink connectors to modify the messages before the sink connectors processes them. You can use SMTs to filter out or mask specific fields, add new fields, modify existing fields, change the topic and/or topic partition to which the messages are written, and even more. And you can even chain multiple SMTs together.

Kafka Connect comes with a number of built-in SMTs that you can simply configure and use, but you can also create your own SMT implementations to do more complex and interesting things. For example, although Debezium connectors normally map all of the changes in each table (or collection) to separate topics, you can write a custom SMT that uses a completely different mapping between tables and topics and even add fields to message keys and/or values. Using your new SMT is also very easy - simply put it on the Kafka Connect classpath and update the connector configuration to use it.

We’ve also added Debezium Docker images labelled 0.5 and latest, which we use in our tutorial.

Thanks to Sanjay and everyone in the community for their help with this release, issues, discussions, contributions, and questions!

What’s next

We’ll continue to improve the MongoDB, MySQL, and PostgreSQL connectors and pushing out 0.5.x releases with fixes. And we’re still working on connectors for SQL Server and Oracle. Stay tuned and get involved!

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.

We hope you find Debezium interesting and useful, and want to give it a try. Follow us on Twitter @debezium, chat with us on Gitter, or join our mailing list to talk with the community. All of the code is open source on GitHub, so build the code locally and help us improve ours existing connectors and add even more connectors. If you find problems or have ideas how we can improve Debezium, please let us know or log an issue.

Debezium 0.4.1 Released


We’re happy to announce that Debezium 0.4.1 is now available for use with Kafka Connect 0.10.1.1. This release includes several fixes for the MongoDB connector and MySQL connector, including improved support for Amazon RDS and Amazon Aurora (MySQL compatibility). See the release notes for specifics on these changes.

We’ve also updated the Debezium Docker images labelled 0.4 and latest, which we use in our tutorial.

Thanks to Jan, Horia, David, Josh, Johan, Sanjay, Saulius, and everyone in the community for their help with this release, issues, discussions, contributions, and questions!

What’s next

Kafka 0.10.2.0 is out, so we plan to release 0.5.0 next week with all of the changes/fixes in 0.4.1 but with support for Kafka 0.10.2.0. We’ll then continue to improve the MongoDB, MySQL, and PostgreSQL connectors and pushing out 0.5.x releases. Stay tuned and get involved!

PostgreSQL support added to Debezium


With the recent Debezium release, we’re happy to announce that a new PostgreSQL connector has been added alongside the already existing MySQL and MongoDB connectors.

Tip

Make sure you read the connector documentation for an in-depth look at the different configuration options.

Getting started

The fastest way to check out the new connector is using Debezium’s Postgres docker image which is based on a vanilla Postgres docker image on top of which it compiles and installs a PostgreSQL logical decoding plugin and sets up the necessary permissions for streaming changes locally (on localhost)

Once you fire up the Docker machine with the database server, starting up and configuring the connector to stream changes from that machine is exactly the same as described in detail by the Debezium tutorial. The only obvious difference is that instead of the MySQL machine and MySQL connector configuration you need to use the PostgreSQL machine and the PostgreSQL connector configuration parameters.

Using the connector in your own environment

Unlike the Mongo and MySQL connectors, getting the PostgreSQL connector up and running is a bit more complicated due to the fact that it requires a server-side logical decoding plugin running in the PostgreSQL server.

In general, there are three major steps involved in getting the connector running in your environment:

  1. Compiling and installing the logical decoding plugin into your own server

  2. Setting up the PostgreSQL server with appropriate replication permissions

  3. Starting the Kafka Connect, Broker and Zookeeper machines

For steps 1 and 2 you can check out our PostgreSQL Docker image together with the sources for the logical decoding plugin

For step 3 you can either use Debezium’s Kafka Docker images or perform a similar setup locally. The Debezium tutorial and the the connector documentation are great resources for helping out with this task.

Debezium 0.4.0 Released


We’re happy to announce that Debezium 0.4.0 is now available for use with Kafka Connect 0.10.1.1. This release introduces a new PostgreSQL connector, and contains over a dozen fixes combined for the MongoDB connector and MySQL connector, including preliminar support for Amazon RDS and Amazon Aurora (MySQL compatibility). See the release notes for specifics on these changes.

We’ve also created Debezium Docker images labelled 0.4 and latest, which we use in our tutorial.

Thanks to Horia, Chris, Akshath, Ramesh, Matthias, Anton, Sagi, barton, and others for their help with this release, issues, discussions, contributions, and questions!

What’s next

We’ll continue to improve the MongoDB, MySQL, and PostgreSQL connectors and pushing out 0.4.x releases. We’re also going to work on a few new connectors, though we’ll likely increase the minor version with each new connector. Stay tuned and get involved!

Debezium 0.3.6 Released


We’re happy to announce that Debezium 0.3.6 is now available for use with Kafka Connect 0.10.0.1. This release contains over a dozen fixes combined for the MySQL connector and MongoDB connectors. See the release notes for specifics on these changes.
