Description

We have low test coverage regarding querying pre-partitioned data. There's at least 1 known bug: https://github.com/datafusion-contrib/datafusion-distributed/issues/310

It would be useful to add partitioning to our large scale tests somehow and validate correctness.

Research direction

Start by reading the existing tpch and tpcds tests and the known bug in issue #310. Add partitioned-data cases to the large-scale tests and validate that their query results are correct; done means the tests cover pre-partitioned data and detect the reported failure.
