-----------------------------------

             Summary: Add stream-stream non-window cross join
                 Key: FLINK-11070
                 URL: https://issues.apache.org/jira/browse/FLINK-11070
             Project: Flink
          Issue Type: New Feature
          Components: Table API &amp; SQL
            Reporter: Hequn Cheng
            Assignee: Hequn Cheng


Currently, stream-stream non-window cross join has not been supported. It would be nice to
support it on streaming. We can start from a simple version, for example, call forceNonParallel()
for connectOperator in `DataStreamJoin` when it is a cross join. Optimizations can be done
later, such as broadcasting the smaller side, etc.
Any suggestions are greatly appreciated.
