> 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.
