Apache Kafka has announced the release of version 4.0.0, marking a significant milestone as it operates entirely without Apache ZooKeeper, simplifying deployment and management. This release introduces KRaft mode by default, which reduces operational overhead and enhances scalability. Key features include the general availability of KIP-848, which improves consumer group rebalance performance, and early access to KIP-932, allowing Kafka to support traditional queue semantics. The release also removes deprecated APIs, requiring Kafka Clients and Streams to use Java 11, while Brokers, Connect, and Tools now require Java 17. Other notable improvements include enhancements to consumer protocols, metrics collection, and error handling in Kafka Streams. The upgrade path for clients and tools has been clarified, and the logging framework has been updated to Log4j2. Overall, Kafka 4.0.0 continues to evolve to meet modern data streaming and messaging needs.
