Brian Hulette commented on BEAM-14162:
--------------------------------------
Categorized this as a bug for now since I'm not sure how we handle this now. We
probably fail in a not-very-helpful way.
> 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
> Priority: P2
>
> 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.
