AWS – Amazon MSK launches support for KRaft mode for new Apache Kafka clusters

Amazon Managed Streaming for Apache Kafka (Amazon MSK) now supports KRaft mode (Apache Kafka Raft) in Apache Kafka version 3.7. The Apache Kafka community developed KRaft to replace Apache ZooKeeper for metadata management in Apache Kafka clusters. In KRaft mode, cluster metadata is propagated within a group of Kafka controllers, which are part of the Kafka cluster, versus across ZooKeeper nodes. On Amazon MSK, like with ZooKeeper nodes, KRaft controllers are included at no additional cost to you, and require no additional setup or management.

You can now create clusters in either KRaft mode or ZooKeeper mode on Apache Kafka version 3.7. In Kraft mode, you can add up to 60 brokers to host more partitions per-cluster, without requesting a limit increase, compared to the 30-broker quota on Zookeeper-based clusters. Support for Apache Kafka version 3.7 is offered in all AWS regions where Amazon MSK is available. To learn more about KRaft on MSK, read our launch blog and FAQs. To get started with Amazon MSK, see the Amazon MSK Developer Guide.
