---------------------------------------------

             Summary: 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
         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
