Spring For Apache Kafka 2.0 and 1.3 Release Candidates Available

Releases | Gary Russell | September 12, 2017 | ...

We are pleased to announce the availability of the 2.0.0.RC1 release candidate of the Spring for Apache Kafka 2.0 version.

As discussed in the 1.3.0.M2 announcement, we are concurrently releasing 1.3 with 2.0, where 1.3 contains a subset of the 2.0 features, supporting the Kafka 0.11.x.x client, while still supporting Spring Framework 4.3. As such, the 1.3.0.RC1 release candidate is also available.

They are available for download from the Milestone Repository:

repositories {
    maven { url 'http://repo.spring.io/libs-milestone' }
}
compile "org.springframework.kafka:spring-kafka:2.0.0.RC1"

Since the previous announcement, the following is a summary of additional features added:

  • Support for Spring Framework’s transaction synchronization.

  • KafkaAdmin is now available to automatically add topics (for NewTopic beans present in the application context).

  • AckMode.RECORD now correctly commits the offset immediately after the listener returns. This is facilitated by the new threading model in the listener container.

  • Several bug fixes

These features are also available in the 1.3 release.

Thanks to all community members for any feedback and contributions!

General availability of the 2.0 release will be shortly after the Spring Framework 5.0 release. Feedback, feature requests and, of course, contributions are welcomed via the usual channels:

In addition, spring-integration-kafka milestones (3.0.0.M2 for spring-kafka 2.0, and 2.3.0.RC1 for spring-kafka 1.3, and 2.2.0.M1 for spring-kafka 1.2 are also available in the milestone repository.

Also the maintenance version spring-integration-kafka-2.1.2.RELEASE is available with ErrorMessageStrategy and sendFailureChannel support for the KafkaProducerMessageHandler. At the same time the success (SendResult.getRecordMetadata()) of the publishing to the topic is sent to the outputChannel as a kafka_recordMetadata header together with the requstMessage as payload.
