             Summary: Support to consume retractions for OVER WINDOW operator
                 Key: FLINK-19059
                 URL: https://issues.apache.org/jira/browse/FLINK-19059
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / Planner
            Reporter: Jark Wu


Currently, OVER WINDOW in streaming SQL only support to consume insert-only stream and doesn't support to consume retractions (i.e. contains UPDATE/DELETE messages). This results in OVER WINDOW can't be used to follow after unbounded group by or streaming join.
