Roman Khachatryan updated FLINK-20103:
--------------------------------------
Description:
This is a follow-up ticket after FLINK-20097.
The current setup (UnalignedITCase) doesn't reveal:
- race conditions (1 per tens of runs)
- or bugs triggered in some specific setup (low checkpoint timeout)
Changes that might hide the bugs:
- having Preconditions in ChannelStatePersister (slow down processing)
- some Preconditions may mask errors by causing job restart
- timings in tests (UnalignedITCase)
An additional issue with the current setup is that it's difficult to git bisect
(for long ranges).
