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!
The main features of this release is the new Debezium Signaling Table support, Vitess SET type support, and a continued focus to minor improvements, bugfixes, and polish as we sprint to the finish line for the 1.5 release.
Overall, the community fixed 54 issues since the Beta1 release, some of which we’ll explore more in-depth below.
I’m very happy to announce the release of Debezium 1.5.0.Beta1!
This release adds a brand-new component — the web-based Debezium UI --, transaction metadata support for the MySQL connector, a large number of improvements to the LogMiner-based capture implementation for the Debezium Oracle connector, support for Vitess 9.0, and much more. Let’s explore some of the new features in the following.
It’s my pleasure to announce the first release of the Debezium 1.5 series, 1.5.0.Alpha1!
This release brings many improvements to the LogMiner-based capture implementation for the Debezium Oracle connector, a large overhaul of the MySQL connector, as well as a wide range of bug fixes and other small feature additions.
I’m pleased to announce the release of Debezium 1.4.1.Final!
We highly recommend upgrading from 1.4.0.Final and earlier versions as this release includes bug fixes and enhancements to several Debezium connectors which includes some of the following:
I am pleased to announce the release of Debezium 1.4.0.Final!
This release concludes the major work put into Debezium over the last three months. Overall, the community fixed 117 issues during that time, including the following key features and changes:
Fine-grained selection of snapshotted tables
MySQL support for create or read records emitted during snapshot
Many Oracle Logminer adapter improvements
Full support for Oracle JDBC connection strings
Improved reporting of DDL errors
I’m excited to announce the release of Debezium 1.3.1.Final!
This release primarily focuses on bugs that were reported after the 1.3 release. Most importantly, the following bugs were fixed related to the Debezium connector for Oracle LogMiner adapter thanks to the continued feedback by the Debezium community.
Welcome to the first edition of "Debezium Community Stories With…", a new series of interviews with members of the Debezium and change data capture community, such as users, contributors or integrators. We’re planning to publish more parts of this series in a loose rhythm, so if you’d like to be part of it, please let us know. In today’s edition it’s my pleasure to talk to Renato Mefi, a long-time Debezium user and contributor.
It’s with great please that I’m announcing the release of Debezium 1.3.0.Final!
As per Debezium’s quarterly release cadence, this wraps up the work of the last three months. Overall, the community has fixed 138 issues during that time, including the following key features and changes:
A new incubating LogMiner-based implementation for ingesting change events from Oracle
Support for Azure Event Hubs in Debezium Server
Upgrade to Apache Kafka 2.6
Revised filter option names
A new SQL Server connector snapshot mode,
Support for database-filtered columns for SQL Server
Additional connection options for the MongoDB connector
ByteBufferConverterfor implementing the outbox pattern with Avro as the payload format
I’m very happy to announce the release of Debezium 1.3.0.CR1!
As we approach the final stretch of Debezium 1.3 Final, we took this opportunity to add delegate converter support for the
ByteBufferConverter and introduce a
debezium-scripting module. In addition, there’s also a range of bug fixes and quite a bit of documentation polish; overall, not less than 15 issues have been resolved for this release.
I’m very happy to announce the release of Debezium 1.3.0.Beta2!
In this release we’ve improved support for column filtering for the MySQL and SQL Server connectors, and there’s a brand-new implementation for ingesting change events from Oracle, using the LogMiner package. As we’re on the home stretch towards Debezium 1.3 Final, there’s also a wide range of smaller improvements, bug fixes and documentation clarifications; overall, not less than 44 issues have been resolved for this release.
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.
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.
This article is a dive into the realms of Event Sourcing, Command Query Responsibility Segregation (CQRS), Change Data Capture (CDC), and the Outbox Pattern. Much needed clarity on the value of these solutions will be presented. Additionally, two differing designs will be explained in detail with the pros/cons of each.
So why do all these solutions even matter? They matter because many teams are building microservices and distributing data across multiple data stores. One system of microservices might involve relational databases, object stores, in-memory caches, and even searchable indexes of data. Data can quickly become lost, out of sync, or even corrupted therefore resulting in disastrous consequences for mission critical systems.
Solutions that help avoid these serious problems are of paramount importance for many organizations. Unfortunately, many vital solutions are somewhat difficult to understand; Event Sourcing, CQRS, CDC, and Outbox are no exception. Please look at these solutions as an opportunity to learn and understand how they could apply to your specific use cases.
As you will find out at the end of this article, I will propose that three of these four solutions have high value, while the other should be discouraged except for the rarest of circumstances. The advice given in this article should be evaluated against your specific needs, because, in some cases, none of these four solutions would be a good fit.
Outbox as in that folder in my email client? No, not exactly but there are some similarities!
The term outbox describes a pattern that allows independent components or services to perform read your own write semantics while concurrently providing a reliable, eventually consistent view to those writes across component or service boundaries.
You can read more about the Outbox pattern and how it applies to microservices in our blog post, Reliable Microservices Data Exchange With the Outbox Patttern.
So what exactly is an Outbox Event Router?
