Till Rohrmann commented on FLINK-22682:
---------------------------------------
The {{DefaultCompletedCheckpointStore}} should log {{"Added {} to {}",
checkpoint, path}} once it added the checkpoint on debug. This could help
verifying the suspicion.
> 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
> Priority: Major
>
> 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.
