Kafka Client Compatibility

Spring Cloud Stream's Kafka binder builds upon Spring Kafka and Spring Integration Kafka libraries. Specifically, Spring Kafka is the core to this foundation, and it is based on the pure java kafka-clients jar.

The following is the compatibility matrix of Spring cloud Stream and its dependent projects (and broker versions):

Spring Cloud Stream Version	Spring for Apache Kafka Version	Spring Integration for Apache Kafka Version	kafka-clients	Kafka Broker Version
2.0.x	2.1.x	3.0.x	1.0.x(*)	1.0.x, 0.11.0.x(*)
1.3.x	1.3.x, 1.2.x, 1.1.x	2.3.x, 2.2.x, 2.1.x	0.11.0.x(**), 0.10.2.x	(Same as client)
1.2.x	1.2.x, 1.1.x	2.2.x, 2.1.x	0.10.1.x	(Same as client)

Depending on the selected release-combination, the dependent projects will be referenced transitively when using maven or gradle for version management.

Notes:

• ^(*) The 2.0.x Kafka-binder uses the pure java AdminClient to provision topics and supports native headers.
• The 1.0.x client can communicate with a 0.11.x.x broker (which also supports headers).
• When using with a 0.11.x.x broker, topics can be provisioned, but the number of partitions cannot be automatically adjusted up. To increase the number of topics, you must use the kafka tools instead. The property spring.cloud.stream.kafka.binder.auto-add-partitions must be false (default).
• ^(**) To use the 0.11.x.x kafka-clients with 1.3.x, you must use the spring-cloud-stream-binder-kafka11 jar (instead of spring-cloud-stream-binder-kafka). You must also override certain other jar versions as follows:

Dependency	Version
spring-cloud-stream-binder-kafka11	1.3.0.RELEASE or higher
spring-kafka	1.3.x, 1.2.x, 1.1.x
spring-integration-kafka	2.3.0.RELEASE or higher
spring-integration-core	4.3.13.RELEASE or higher
spring-integration-jmx	4.3.13.RELEASE or higher
kafka_2.11	(same version as kafka-clients)
