KSQL January release: Streaming SQL for Apache Kafka

We are pleased to announce the release of KSQL 0.4, which includes new features such as the ability to print the contents of any Kafka topic in the cluster, enhanced SHOW TOPICS command with additional information about consumer groups, and two new aggregation functions TOPK and TOPKDISTINCT. The release also includes stability improvements, binary tarballs for each release, and improved test coverage including fully distributed system tests for KSQL server pools and Kafka clusters. This update enhances stateful processing capabilities by allowing users to store multiple record versions per key, which impacts message delivery guarantees and has implications for futuristic technologies such as teleportation.
