The Spring Integration for Apache Kafka extension project provides inbound and outbound channel adapters and gateways for Apache Kafka. Apache Kafka is a distributed publish-subscribe messaging system that is designed for high throughput (terabytes of data) and low latency (milliseconds). For more information on Kafka and its design goals, see the Kafka main page.
Starting from version 2.0 version this project is a complete rewrite based on the new
spring-kafka project which uses the pure java "new" Producer and
Consumer clients provided by Kafka.
See the Spring Integration kafka Sample for a simple Spring Boot application that sends and receives messages.
In order to build the project:
./gradlew build
In order to install this into your local maven cache:
./gradlew install
Documentation for this extension is contained in a chapter of the Spring for Apache Kafka Reference Manual
Producer record metadata for sends performed on the outbound channel adapter are now sent only to the successChannel.
With earlier versions, it was sent to the outputChannel if no successChannel was provided.
