Jingsong Lee updated FLINK-23350:
---------------------------------
Description: (Copy from FLINK-20374) We can start documenting the change
log behavior of the planner in our docs as part of this FLINK-20374. Users
should get more insights what the planner is doing. It is too much of a black
box right now. It is very difficult to interpret why and when +U,-U or special
operators are inserted into the pipeline.
> Write doc for change log disorder by special operators
