We are pleased to announce the availability of the Milestone 3 of the Spring for Apache Kafka 2.0 version.

It is 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.M3"

Since the previous announcement, these feature have made it into the current Milestone:

• Apache Kafka 0.11.0.0 client base line;

• With the new Apache Kafka foundation we have introduced KafkaTransactionManager and transactions support in the KafkaTemplate via new executeInTransaction() operation;

• The KafkaListenerContainer can now be supplied with the TransactionManager to perform polling and offset commits with transaction boundaries;

• The Kafka Headers support is provided as well. Now you can send and receive messages with any arbitrary headers, for example build request-reply scenarios using some correlationKey header;

• The ConsumerAwareErrorHandler is provided to manage Consumer state in case of errors;

• The KafkaEmbedded can now be supplied with any arbitrary brokerProperties.

Thanks to all community members for any feedback and contributions!

General availability of the 2.0 release is expected to be in the September (shortly after the Spring Framework 5.0 release). Feedback, feature requests and, of course, contributions are welcomed via the usual channels:
