             Summary: Support split distinct aggregate for window TVF based aggregate
                 Key: FLINK-21304
                 URL: https://issues.apache.org/jira/browse/FLINK-21304
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Jark Wu
             Fix For: 1.13.0


Currently, optimization {{table.optimizer.distinct-agg.split.enabled}} is only supported for unbounded aggregate. It is a very important optimization for skewed distinct aggregates, and we also need this optimization for window TVF based aggregate.
