Spring For Apache Kafka 1.3 Milestone 2 Available
We are pleased to announce the availability of the Milestone 2 of the Spring for Apache Kafka 1.3
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:1.3.0.M1"
(Milestone 1 had a blocker issue).
Functionally, the 1.3.x line provides a subset of the 2.0 line (which requires Spring Framework 5.0 and Java 8), but provides support for Java 7 projects and Spring Framework 4.3.x
.
It is primarily intended to provide early access to 0.11.0.0 Apache Kafka client features, but here is a summary:
-
Apache Kafka 0.11.0.0 client;
-
Improved listener container threading model facilitated by KIP-62;
-
With the new Apache Kafka foundation we have introduced the
KafkaTransactionManager
and local transaction support in theKafkaTemplate
via newexecuteInTransaction()
operation; -
The
KafkaListenerContainer
can now be supplied with aTransactionManager
to perform polling and offset commits with transaction boundaries, and to synchronize a Kafka transaction with some external transaction manager. -
Support for the new Kafka
Headers
feature is also provided. Now you can send and receive messages with any arbitrary headers, for example build request-reply scenarios using somecorrelationKey
header; -
The
KafkaEmbedded
JUnit class/Spring Bean can now be supplied with any arbitrarybrokerProperties
; -
The
KafkaAdmin
can be used to automatically create topics by scanning the application context forNewTopic
beans.
In addition, Spring Integration extension for Apache Kafka 2.3.0.M2 is available to incorporate the Spring for Apache Kafka 1.3
foundation.
In particular the KafkaProducerMessageHandler
can be supplied with the KafkaHeaderMapper
, where the DefaultKafkaHeaderMapper
is used by default if the Jackson JSON processor is present in the classpath. If also includes enhancements to error handling.
spring-integration-kafke 2.2.0.M1 is also available for spring-kafka 1.2.x. It includes the enhanced error handling mentioned above.
See the Project Page for a complete matrix of spring-kafka, spring-integration-kafka and kafka-clients version compatibility.
