>             Project: Flink
>          Issue Type: Improvement
>          Components: API / State Processor, Runtime / State Backends
>            Reporter: 刘方奇
>            Priority: Major

> As the title, in the state-processor-api, we use the savepoint opition to 
> snapshot state defaultly in org.apache.flink.state.api.output.SnapshotUtils.
> But in many cases, we maybe need to snapshot state incremently which have 
> better performance than savepoint.
> Shall we add the config to chose the checkpoint way just like flink stream 
> backend?
