The Teradata Connector for Trino enables Trino to connect to Teradata Vantage.

This repository is maintained by Teradata for the development and distribution of the Teradata Connector for Trino.

Documentation

For installation, configuration, supported features, and usage information, see the Teradata Connector for Trino documentation.

Releases

Tested versions of the Teradata Connector for Trino are published under GitHub Releases. Each release is identified by a tag of the form teradata-trino-<trino-version>. The release version always matches the Trino version it is built for (for example, teradata-trino-482 is built for Trino 482).

Customers should use published releases rather than the teradata-development branch.
