[GitHub] [beam] TheNeuralBit opened a new issue, #21827: [Task]: grouping on categorical columns should not require Singleton partitioning

TheNeuralBit opened a new issue, #21827:
URL: https://github.com/apache/beam/issues/21827

   ### What needs to happen?
   
   Currently groupby with observed=False (the default) requires aggregating in the Singleton partition since it would otherwise produce results with every index value within every partition.
   
   Originally reported in BEAM-11190, which was erroneously closed at the time of the migration to GitHub Issues.
