-----------------------------------------------
Hi [~raviratnakar] from the git history, the code at line number 1512 was added
in 1.9.0(and seems there change would not affect this problem), IIUC, we would
check whether the checkpoint can be triggered somewhere, I need to check it
carefully as the code changed a lot. will reply here If found anything.
> Checkpoint not maintaining minimum pause duration between checkpoints

> Key: FLINK-18675
> URL: https://issues.apache.org/jira/browse/FLINK-18675
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.11.0
> Environment: !image.png!
> Reporter: Ravi Bhushan Ratnakar
> Priority: Critical
> Attachments: image.png
>
>
> I am running a streaming job with Flink 1.11.0 using kubernetes
> infrastructure. I have configured checkpoint configuration like below
> Interval - 3 minutes
> Minimum pause between checkpoints - 3 minutes
> Checkpoint timeout - 10 minutes
> Checkpointing Mode - Exactly Once
> Number of Concurrent Checkpoint - 1
>
> Other configs
> Time Characteristics - Processing Time
>
> I am observing an usual behaviour. *When a checkpoint completes successfully*
> *and if it's end to end duration is almost equal or greater than Minimum
> pause duration then the next checkpoint gets triggered immediately without
> maintaining the Minimum pause duration*. Kindly notice this behaviour from
> checkpoint id 194 onward in the attached screenshot
