[GitHub] [beam] damccorm opened a new issue, #21594: DataFrame groupby does not support Grouper objects

damccorm opened a new issue, #21594:
URL: https://github.com/apache/beam/issues/21594

   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.
   
   Imported from Jira [BEAM-14162](https://issues.apache.org/jira/browse/BEAM-14162). Original Jira may contain additional context.
