KIPs and more: https://www.confluent.io/blog/introducing-apache-kafka-4-0 | Tim Berglund (Developer Relations, Confluent) is in Mumbai, India to break down the exciting new features in Apache Kafka 4.0. With the introduction of more cloud-native enhancements, Kafka is evolving to meet the demands of modern architectures. Key updates include the complete removal of ZooKeeper with KRaft now handling metadata, improvements to the consumer rebalance protocol, and the introduction of experimental Queue functionality with KIP-932. Additionally, 4.0 brings enhancements to Kafka Streams, better observability, and more efficient error handling.
