LOL. I think I found a way:
1. Rebase #3764 over to current master;
2. Rebase this branch to the rebased #3764;
3. Make changes on top
:-)
> Support distinct aggregation on group windowed streaming tables.

> Priority: Major

> We are proposing to reuse distinct aggregate codegen work designed for
> *FlinkLogicalOverAggregate*, to support unbounded distinct aggregation on
> datastream as well.
