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