Xiao Huang updated FLINK-35409:
-------------------------------
Description:
Suppose this scenario: A job is still in the snapshot phase, and the remaining
uncompleted snapshot splits all belong to a few tables that have been deleted
by the user.
In such case, when restarting from a savepoint, these uncompleted snapshot
splits will not trigger a call to the addSplits method. Moreover, since the
BinlogSplit has not been sent yet, the job will not start the SplitReader to
read data.
> Request more splits if all splits are filtered from addSplits method
