Chapter 2. Enhancements

For an overview of the enhancements introduced with Kafka 2.4.0, refer to the Kafka 2.4.0 Release Notes.

Distributed tracing using Jaeger is now supported for the Kafka Bridge component of AMQ Streams on Red Hat Enterprise Linux.

The Kafka Bridge generates traces when it sends and receives messages to and from HTTP clients, and when HTTP clients send requests to the Kafka Bridge REST API to create a consumer, retrieve messages, and so on. You can view these traces in the Jaeger user interface.

To enable tracing for the Kafka Bridge, add the following property to the Kafka Bridge properties file:

bridge.tracing=jaeger

You can then deploy the Kafka Bridge to an AMQ Streams cluster on Red Hat Enterprise Linux by running the bin/kafka_bridge_run.sh script.
