Zongwen Li created FLINK-24881:
----------------------------------
Summary: When the Source is back pressured, the checkpoint
interval may not take effect
Key: FLINK-24881
URL: https://issues.apache.org/jira/browse/FLINK-24881
Project: Flink
Issue Type: Bug
Components: API / Core
Affects Versions: 1.13.3, 1.14.0
Reporter: Zongwen Li
Attachments: image-2021-11-12-11-21-15-910.png
Checkpoint config:
* EXACTLY_ONCE
* aligned
* interval: 10s
* min-pause: 10s
* max-attempts: 2
When Source was back pressured for a long time, I found that multiple
checkpoints were triggered at the same time, which made the configuration
support parallel checkpoint and checkpoint interval unable to achieve the
target effect;
And I found that there is usually a checkpoint that will fail at this time, but
this failure will not cause the job to restart.
