Yun Gao updated FLINK-25105:
----------------------------
Release Note:
In 1.15 we enabled the support of checkpoints after part of tasks finished by
default, and make tasks waiting for the final checkpoint before exit to ensures
all data get committed.
However, it needs to note that make tasks waiting for one more checkpoint
before exit would also block the tasks until the next checkpoint get triggered.
If the checkpoint interval is long, the tasks' execution time would also be
extended largely. In the worst case if the checkpoint interval is
Long.MAX_VALUE, the tasks would be in fact blocked forever.
More information about this feature and how to disable it could be found in
