      I want to implement grouping set in stream. I am new to flink sql. I
want to find a example to teach me how to self define rule and
implement corresponding operator. Can anyone give me any suggestion?

AFAIK, grouping sets has already been supported for streaming in blink planner. You could check FLINK-12192 for details.
