> Require unaligned checkpoints to be disabled in StateFun applications
> ---------------------------------------------------------------------
>
> Key: FLINK-20636
> URL: https://issues.apache.org/jira/browse/FLINK-20636
> Project: Flink
> Issue Type: Task
> Components: Stateful Functions
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Labels: pull-request-available
> Fix For: statefun-2.2.2
>
>
> Due to how StateFun has feedback loops, with unaligned checkpoints a function
> dispatcher operator may receive a feedback checkpoint barrier (from other
> parallel subtasks that process the checkpoint barrier first) before it
> receives its own checkpoint barrier.
> We need to further investigate how to properly support unaligned
> checkpointing in StateFun.
> For the time being, we should strictly require aligned checkpointing for
> StateFun apps.
