ksqlDB is a fast moving project. Try the latest additions as soon as possible through the standalone distribution, which is free to use. The source is available on GitHub.

A new release goes out roughly once per month. The current version is 0.11.0. The standalone distribution is licensed under the Confluent Community License and is not commercially supported by Confluent.

Confluent Cloud

Want to skip the hassle of running ksqlDB yourself? Use it as a fully managed service on Confluent Cloud. Focus on building your app instead of your cluster, and just pay for what you use.

The cloud distribution of ksqlDB is transparently upgraded on your behalf. Each cloud version wraps a specific version of the standalone distribution.
