Chapter 3. Features

AMQ Streams 2.5.x is the Long Term Support (LTS) offering for AMQ Streams.

The latest patch release is AMQ Streams 2.5.2. The AMQ Streams binaries have changed to version 2.5.2. Although the supported Kafka version is listed as 3.5.0, it incorporates updates and improvements from Kafka 3.5.2.

For information on the LTS terms and dates, see the AMQ Streams LTS Support Policy.

AMQ Streams supports and uses Apache Kafka version 3.5.0. Updates for Kafka 3.5.2 are incorporated with the 2.5.2 patch release. Only Kafka distributions built by Red Hat are supported.

For upgrade instructions, see AMQ Streams and Kafka upgrades.

Refer to the Kafka 3.5.0, Kafka 3.5.1, and Kafka 3.5.2 Release Notes for additional information.

Kafka 3.4.x is supported only for the purpose of upgrading to AMQ Streams 2.5.

Kafka 3.5.x uses ZooKeeper version 3.6.4, which is a different version to Kafka 3.4.x. We recommend that you perform a rolling update to use the new binaries.

OpenTelemetry for distributed tracing has moved to GA. You can use OpenTelemetry with a specified tracing system. OpenTelemetry has replaced OpenTracing for distributed tracing. Support for OpenTracing is deprecated.

By Default, OpenTelemetry uses the OTLP (OpenTelemetry Protocol) exporter for tracing. AMQ Streams with OpenTelemetry is distributed for use with the Jaeger exporter, but you can specify other tracing systems supported by OpenTelemetry. AMQ Streams plans to migrate to using OpenTelemetry with the OTLP exporter by default, and is phasing out support for the Jaeger exporter.
