[ANNOUNCE] Kafka 3.1.0 Released

Cloudera is pleased to announce the release of CDK 3.1.0 powered by Apache Kafka. Apache Kafka is a highly scalable, distributed, publish-subscribe messaging system. CDK 3.1.0 is a minor release based on Apache Kafka 1.0.1.

 

Notable Issues Fixed in CDK 3.1.0:

  • [KAFKA-5970] - Deadlock due to locking of DelayedProduce and group

  • [KAFKA-6739] - Down-conversion fails for records with headers

  • [KAFKA-6185] - Selector memory leak with high likelihood of OOM in case of down conversion.

  • [KAFKA-6134] - High memory usage on controller during partition reassignment.

  • [KAFKA-6042] - Kafka Request Handler deadlocks and brings down the cluster.

  • [KAFKA-6003] - Replication Fetcher thread for a partition with no data fails to start.

All backported fixes can be viewed in the git release notes here or on our website under the Issues fixed section.
