------------------------------
Summary: 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
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.
