Chapter 1. Features

AMQ Streams now supports Apache Kafka version 3.0.0.

AMQ Streams uses Kafka 3.0.0. Only Kafka distributions built by Red Hat are supported.

For upgrade instructions, see AMQ Streams and Kafka upgrades.

Refer to the Kafka 2.8.0 and Kafka 3.0.0 Release Notes for additional information.

For more information on supported versions, see the Red Hat Streams for Apache Kafka Component Details on the Customer Portal.

Kafka 3.0.0 requires ZooKeeper version 3.6.3. Therefore, you need to upgrade ZooKeeper when upgrading from AMQ Streams 1.8 to AMQ Streams 2.0, as described in the upgrade documentation.

AMQ Streams now uses Scala 2.13, which replaces Scala 2.12.

If you are using the Kafka Streams dependency in your Maven build, you must update it to specify Scala 2.13 and Kafka version 3.0.0. If the dependency is not updated, it will not build.

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-streams-scala_2.13</artifactId>
    <version>3.0.0</version>

AMQ Streams 2.0 is enabled to run on PowerPC ppc64le architecture.

Support for IBM Power systems applies to AMQ Streams running with Kafka 3.0.0 and Open JDK 11 on Red Hat Enterprise Linux 8. The Kafka versions shipped with AMQ Streams 1.8 and earlier versions do not contain the ppc64 binaries.
