The cudf polars tests are run for multiple versions of Polars (oldest and newest supported IIRC). We also have a large matrix of CI jobs running these tests.
It seems probable that we could reduce CI time by running only a single Polars version on each matrix entry, and ensuring that the full matrix covers all polars versions we test. This would approximately halve the test time for each cudf-polars test job.
