Spring for Apache Kafka 1.0 and Spring Integration Kafka 2.0 go GA

Releases
0 Comment

I’m pleased to announce that the spring-kafka (Spring for Apache Kafka) 1.0 GA and Spring Integration Kafka 2.0 GA are available finally!

The artifacts org.springframework.kafka:spring-kafka:1.0.0.RELEASE and org.springframework.kafka:spring-kafka-test:1.0.0.RELEASE are available in the Release repository and Maven Central, respectively.

In addition org.springframework.integration:spring-integration-kafka:2.0.0.RELEASE, fully based on the spring-kafka-1.0.0.RELEASE, is available at the same repositories as well.

Important
 Just after release we figured out a nasty bug with unacked offset commits for RECORD mode. Special thanks to Adam Dec! So, please, meet spring-kafka:1.0.1.RELEASE as well.

Of course, many thanks to everyone involved, to active community members, who provided feature requests and contributions.

There have been some reworks and bug fixes since the Release Candidate 1 including:

  • rework for Manual AckMode, which indicate as a breaking change though, because the MANUAL_IMMEDIATE_SYNC mode has been removed;

  • the ackTime has now 5 seconds as default value. The same as Kafka default auto.commit.interval.ms;

  • the ackCount must be > 0 in case of COUNT and COUNT_TIME mode;

  • a new Spring Integration Kafka support chapter in the Reference Manual.

See also the Reference Manual for more information.

Next Steps

We expect to release the Milestone 1 for version 1.1 enough soon, which will support Kafka 0.10, include some Spring Boot auto configuration and actuator endpoint and much more!
