[GitHub] [beam] damccorm opened a new issue, #20762: groupby cannot aggregate grouped column
damccorm opened a new issue, #20762:
URL: https://github.com/apache/beam/issues/20762
pandas allows you to aggregate on the same column that you are grouping on. Attempting this in the Beam implementation results in an error.
df.groupby('group')[['group', 'foo']].count()
