Contract & Constraints

Contract

The adapter partly supports contract definition.

Concerning the data_type, it is supported but needs to be adjusted for complex types. They must be specified entirely (for instance array<int>) even though they won't be checked. Indeed, as dbt recommends, we only compare the broader type (array, map, int, varchar). The complete definition is used in order to check that the data types defined in athena are ok (pre-flight check).

Constraints

The adapter does not support constraints since constraints don't exist in Athena.
