Export: Great Expectations

Transforms a data contract into a comprehensive Great Expectations JSON suite. If the contract includes multiple models, specify the model with --schema-name.

datacontract export great-expectations datacontract.yaml --schema-name orders

The export builds expectations from the model definition (with a fixed mapping) and from the quality rules of each model (see the expectations gallery).

Additional options​

  • suite_name — the name of the expectation suite. Defaults to a name derived from the model name(s).
  • engine — the execution engine: pandas (in-memory dataframes), spark (Spark dataframes), or sql (SQL databases).
  • sql_server_type — the SQL server type to connect with when engine is sql. Ensures the correct SQL dialect and connection settings are applied.
