@fhueske @stefanobortoli I suggest we merge this temporary solution into
flink (with using a special marker for distinct) until the flink module will be
upgraded to the next calcite release. I have fixed the issue into calcite.
However, the advantages of pushing already this is that:
1) we can reuse the code
2) when we have the distinct marker we can simply modify the check for
distinct for the aggregates in the DataStreamOver
> Distinct procTime with Rows boundaries
