Chapter 1. Features
AMQ Streams 2.4 introduces the features described in this section.
AMQ Streams 2.4 on RHEL is based on Apache Kafka 3.4.0.
To view all the enhancements and bugs that are resolved in this release, see the AMQ Streams Jira project.
1.1. Kafka 3.4.0 support
AMQ Streams now supports Apache Kafka version 3.4.0.
AMQ Streams uses Kafka 3.4.0. Only Kafka distributions built by Red Hat are supported.
For upgrade instructions, see AMQ Streams and Kafka upgrades.
Refer to the Kafka 3.4.0 Release Notes for additional information.
Kafka 3.3.x is supported only for the purpose of upgrading to AMQ Streams 2.4.
For more information on supported versions, see the AMQ Streams Component Details.
Kafka 3.4.0 uses ZooKeeper version 3.6.3, which is the same version as Kafka 3.3.x. We recommend that you perform a rolling update to use the new binaries.
Kafka 3.4.0 provides access to KRaft mode, where Kafka runs without ZooKeeper by utilizing the Raft protocol. KRaft mode is available as a Technology Preview.
