Thanks for reminding. This has been done eons ago ;)
> Execute unaligned checkpoint test on a cluster
> ----------------------------------------------
>
> Key: FLINK-22137
> URL: https://issues.apache.org/jira/browse/FLINK-22137
> Project: Flink
> Issue Type: Sub-task
> Reporter: Arvid Heise
> Priority: Major
> Labels: pull-request-available
>
> Start application and at some point cancel/induce failure, the user needs to
> restart from a retained checkpoint with
> * lower
> * same
> * higher degree of parallelism.
> To enable unaligned checkpoints, set
> * execution.checkpointing.unaligned: true
> * execution.checkpointing.alignment-timeout to 0s, 10s, 1min (for high
> backpressure)
> The primary objective is to check if all data is recovered properly and if
> the semantics is correct (does state match input?).
> The secondary objective is to check if Flink UI shows the information
> correctly:
> * unaligned checkpoint enabled on job level
> * timeout on job level
> * for each checkpoint, if it's unaligned or not; how much data was written
