Review Comment:
Do you mean the attribute name in `StreamPhysicalGroupAggregateBase`?
I was thinking the partial-final is the internal concept for two-phase
aggregate, so tend to omit the 'final' prefix in the base class which I think
can both represents
grouping in one-phase agg and distinguishes from partialGroupings in
two-phase agg.
