Piotr Nowojski commented on FLINK-22815:
----------------------------------------
One more thing. Will recovery from an UC taken in 1.13.1 with broadcast
partitioning work when upgrading to 1.13.2+? I mean will the recovery of
in-flight data stored in broadcast exchange work despite that new UC for that
exchanges will be aligned?

> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.13.1, 1.12.4
> Reporter: Dawid Wysakowicz
> Assignee: Dawid Wysakowicz
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.11.4, 1.14.0, 1.12.5, 1.13.2

>
> Broadcast partitioning can not work with unaligned checkpointing. There
> are no guarantees that records are consumed at the same rate in all
> channels. This can result in some tasks applying state changes
> corresponding to a certain broadcasted event while others don't. In turn
> upon restore, it may lead to an inconsistent state.
