[PECOBLR-330] Support for complex params #559

jprakash-db · 2025-05-19T04:44:06Z

Description

This PR introduces comprehensive support for complex parameter types (ARRAY and MAP) in the Databricks SQL Python client.

Key Changes

Added new parameter classes: ArrayParameter and MapParameter
These classes recursively wrap Python lists and dictionaries and serialize them into the appropriate Thrift structures.
The type inference logic dbsql_parameter_from_primitive is updated to recognize and construct these parameter types, including for nested complex values.
Added the TSparkParamValueArgs which is necessary to be passed as arguements for complex types

Testing

e2e

Added tests to insert and compare the results for nested structures ARRAY<ARRAY<STRING>>, ARRAY<MAP<STRING,INTEGER>>, MAP<STRING,ARRAY<STRING>>

unit

Added tests to verify the convertion of the params into the respective server contract format

If it is not there it will be an empty space, there is already a test suite that inserts NTZ and none NTZ and reads back to compare whether it is equal or not

Is this not an opt-in feature, can't user disable this in favor of existing behavior?

@gopalldb We are just adding support for more types, don't think there is anything to opt in. If the users don't use complex types they won't need this
