[jira] [Created] (BEAM-14162) DataFrame groupby does not support Grouper objects

Brian Hulette created BEAM-14162:
------------------------------------

             Summary: DataFrame groupby does not support Grouper objects
                 Key: BEAM-14162
                 URL: https://issues.apache.org/jira/browse/BEAM-14162
             Project: Beam
          Issue Type: Bug
          Components: dsl-dataframe
            Reporter: Brian Hulette


pandas has the concept of a [Grouper|https://pandas.pydata.org/docs/reference/api/pandas.Grouper.html], which can be passed to groupby to provide additional metadata. Currently we don't support these in the DataFrame API, we assume all arguments are just labels.

We should explicitly reject these for now, then add support for them.
