David Li commented on ARROW-5022:
---------------------------------
What is left to do here? We added scalar aggregation over scalars in
ARROW-9056, and for hash aggregation, I don't think it makes sense to support
anything but arrays. So going forward we should just make sure to support
scalars and arrays in scalar aggregation.
