This project is a test compatibility kit (TCK) for streaming SQL.

If you are the author of an engine that supports streaming extensions to SQL, you can run these tests to find out whether your engine is compliant.

This project is more than a test suite; it is a living specification. The tests in the latest release represent what is considered valid; new features are under development in branches, pull requests and issues, and when complete, will be voted upon in the next release. Many of the members participate in projects of the Apache Software Foundation, and we run this project according to the Apache Way.

This is a community project, evolving the semantics of SQL by open discussion and consensus. We welcome new members.

Get involved by joining the mailing list (we use the Apache Calcite developers list because it exists, is archived and is reasonably low-volume), contributing test cases via pull requests, and reviewing other people's proposed changes.

We would especially like contributions of documentation (for example, describing streaming SQL's intent and semantics on this site) and richer test cases.

If you are the author of a streaming engine, use the TCK in your test suite! The latest release of the TCK is on Maven Central, so is easy to include.

Get Stream-SQL-TCK from Maven Central:

<dependency>
  <groupId>net.hydromatic</groupId>
  <artifactId>stream-sql-tck</artifactId>
  <version>0.1</version>
