caneff opened a new issue, #28638: URL: https://github.com/apache/beam/issues/28638
### What happened? When trying to support Pandas 2.1, `pytest frames_test.py::GroupByTest::test_groupby_level_agg_3` fails with ```python E AssertionError: Expression does not preserve partitioning! E Expression: ComputedExpression[pre_combine_max_Series_139900651301776] E Requires: Arbitrary E Preserves: Arbitrary E Input partitioning: Index E Expected output partitioning: Index ``` Also, `test_groupby_level_agg_6` fails the same way. Note if I change `test_groupby_level_agg_3` in the parameterized setup to be `[3,0]` instead of `[0, 3]` (so the categorical is first instead of last) it doesn't fail, but if I change `test_groupby_level_agg_3` from `[1, 'str']` to `['str', 1]` it still fails, so it isn't a clearcut answer there. I suspect this and #28637 are intertwined. ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [X] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
