> 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: Critical
> Labels: stale-critical
> Fix For: 1.14.0
>
>
> 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.
