Event Streaming Database

Easily build event streaming applications that leverage stream processing

ksqlDB enables you to build event streaming applications with the same ease and familiarity of building traditional applications on a relational database. It also simplifies the underlying architecture for these applications so you can build powerful, real-time systems with just a few SQL statements.

Confluent Platform ksqlDB

Are you part of a business that wants to use ksqlDB in a mission critical setting? Try the distribution shipped with Confluent Platform, which includes plugins for using ksqlDB in crucial environments, such as RBAC. Enterprise support for ksqlDB is available through a subscription to Confluent Platform.

Note: some ksqlDB features in this distribution are currently in preview (pull queries and embedded connectors), meaning they are not yet supported in production environments.

Each new version of the Confluent Platform distribution builds on a specific, previously shipped version of the standalone distribution. See the version matrix for more detail.
