------------------------------------------
I will double check it, but I think it should be fine.

> Key: FLINK-22815
> URL: https://issues.apache.org/jira/browse/FLINK-22815
> 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.
