Import: Trino

Creates a data contract from a Trino catalog by reading information_schema, including the declared column types and nullability.

datacontract import trino \
  --source localhost \
  --catalog my_catalog \
  --schema my_schema \
  --output datacontract.yaml

--source is the host of your Trino coordinator. Add --port if it doesn't listen on the default 8080, and repeat --table to import only specific tables.

Trino reports a complete type string, so varchar(36), decimal(10,2) and array(varchar) are taken verbatim and match what datacontract test reads back.

The generated contract includes a ready-to-test servers block, so you can run datacontract test datacontract.yaml immediately afterwards — see the Trino connection guide for the full 5-minute walkthrough and troubleshooting.

Credentials are the same ones datacontract test uses — see the Trino Reference.

Only have a DDL script? Use datacontract import sql --dialect postgres; Trino's ANSI-style DDL generally parses with that dialect.
