KSQL, the streaming SQL engine for Apache Kafka, has released its first update since launching at Kafka Summit San Francisco in August. The update includes addressing community-raised issues and requests from the developer preview. KSQL is an open source, distributed, scalable, fault-tolerant, and real-time stream processing tool that supports a wide range of operations including filtering, transformations, aggregations, joins, windowing, sessionization, and more. The community-driven effort aims to make the world of Kafka and stream processing accessible to a broader audience. Future updates will be released on a monthly basis, with a beta program also in the works.
