--------------------------------
[~dwysakowicz] hello，Currently, the stop-with-savepoint [-drain] parameter will
block the source task if it is true, but why not block the source task if it is
false?
If I want to stop the job and then recover from savepoint, the data will be
consumed repeatedly if the source task is not blocked.
