If you are using OAuth 2.0 for token-based authentication, you can now also use Keycloak to configure authorization rules to constrain client access to Kafka brokers.

Red Hat Single Sign-On 7.3 does not support this Technoloy Preview of OAuth 2.0 token-based authorization. If you wish to try this feature, it is tested for use in a development environment with Keycloak 8.0.2 as the authorization server.

AMQ Streams supports the use of OAuth 2.0 token-based authorization through Keycloak Authorization Services, which allows you to manage security policies and permissions centrally.

Security policies and permissions defined in Keycloak are used to grant access to resources on Kafka brokers. Users and clients are matched against policies that permit access to perform specific actions on Kafka brokers.

See Using OAuth 2.0 token-based authorization.

You can now use MirrorMaker 2.0 with AMQ Streams.

MirrorMaker 2.0 is based on the Kafka Connect framework, connectors managing the transfer of data between clusters.

MirrorMaker 2.0 uses:

MirrorMaker 2.0 introduces an entirely new way of replicating data in clusters. If you choose to use MirrorMaker 2.0, there is currently no legacy support, so any resources must be manually converted into the new format.

See Using AMQ Streams with MirrorMaker 2.0.

Debezium for Change Data Capture is a distributed platform that monitors databases and creates change event streams. Debezium is built on Apache Kafka and can be deployed and integrated with AMQ Streams. Following a deployment of AMQ Streams, you deploy Debezium as a connector configuration through Kafka Connect. Debezium captures row-level changes to a database table and passes corresponding change events to AMQ Streams on Red Hat Enterprise Linux. Applications can read these change event streams and access the change events in the order in which they occurred.

Debezium has multiple uses, including:

Debezium provides connectors (based on Kafka Connect) for the following common databases:
