Yuan Mei commented on FLINK-25261:
----------------------------------
Upon offline discussion, there are two more questions/problems related. I will
extract them and open a separate ticket, and discuss whether/how to handle them
before 1.15.
For truncation upon materialization, it is wrapped in the mailbox, so it should
work fine regarding the race condition mentioned above. It does not block
checkpoint snapshots as well, because what to upload/not upload is decided in
the task thread fairly fast; while the real uploading is done asycnously.
