> Checkpoint interval too large for higher DOP
> --------------------------------------------
>
> Key: FLINK-22682
> URL: https://issues.apache.org/jira/browse/FLINK-22682
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.14.0, 1.13.1
> Reporter: Arvid Heise
> Assignee: Anton Kalashnikov
> Priority: Major
> Labels: pull-request-available
>
> When running a job on EMR with DOP of 160, checkpoints are not triggered at the set interval. I used an interval of 10s and the average checkpoint took <10s, so I'd expect ~6 checkpoints per minute.
> However, the actual completion message was heavily delayed. I had backpressure in this test and used unaligned checkpoints.
