[jira] [Updated] (FLINK-22805) Dynamic configuration of Flink checkpoint interval
[ https://issues.apache.org/jira/browse/FLINK-22805?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yun Gao updated FLINK-22805:
----------------------------
Fix Version/s: 1.16.0
> Dynamic configuration of Flink checkpoint interval
> --------------------------------------------------
>
> Key: FLINK-22805
> URL: https://issues.apache.org/jira/browse/FLINK-22805
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Checkpointing
> Affects Versions: 1.13.1
> Reporter: Fu Kai
> Priority: Major
> Labels: auto-deprioritized-critical
> Fix For: 1.15.0, 1.16.0
>
>
> Flink currently does not support dynamic configuration of checkpoint interval on the fly. It's useful for use cases like backfill/cold-start from a stream containing whole history.
>
> In the cold-start phase, resources are fully utilized and the back-pressure is high for all upstream operators, causing the checkpoint timeout constantly. The real production traffic is far less than that and the provisioned resource is capable of handling it.
>
> With the dynamic checkpoint interval configuration, the cold-start process can be speeded up with less frequent checkpoint interval or even turned off. After the process is completed, the checkpoint interval can be updated to normal.
