    Description

      Now, Flink just discard late data when using interval-join:

      https://github.com/apache/flink/blob/83a2541475228a4ff9e9a9def4049fb742353549/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/operators/co/IntervalJoinOperator.java#L231 

       

      Maybe we could use two outputTags to side output late data for left/right stream.
