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

             Summary: Show the maximum parallelism (number of key groups) of a 
job in Web UI
                 Key: FLINK-25068
                 URL: https://issues.apache.org/jira/browse/FLINK-25068
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Web Frontend
    Affects Versions: 1.14.0
            Reporter: zlzhang0122


Now, Flink use maximum parallelism as the number of key groups to distribute 
the key, the maximum parallelism can be set manually, or flink will set-up 
automatically, sometimes the value is useful and we may want to know it, maybe 
we can expose in the Web UI.

By doing this, we can easily know the max parallelism we can suggest the user 
to scale when they are facing the leak of through-output, and we can know which 
subtask will processing the special value and we can find the log soon.
