Rong Rong updated FLINK-8688:
-----------------------------
Description:
Distinct aggregation is not currently supported on data stream with Table/SQL
API. This is an umbrella task for enabling distinct aggregation in various use
cases.

]
Distinct aggregation is a very important feature in SQL processing and there
are many JIRAs currently open with various use cases. The goal is to create one
solution to both unbounded and bounded distinct aggregation on data stream so
that it can easily be extended to support these use cases.
