kSQLDB

Streaming SQL database purpose-built for Kafka

About kSQLDB

A streaming SQL engine for Apache Kafka that lets users build stream processing applications with SQL statements, including joins, aggregations and windowing over event streams. It offers a free entry point, with paid cloud or enterprise tiers adding hosted operation, advanced features, support or higher limits for teams that outgrow self-hosting. That model lets individuals evaluate it on real work first, then pay only when collaboration, scale, compliance or convenience requirements justify a subscription for the whole organisation.
