             Summary: state processor api do not support increment checkpoint
                 Key: FLINK-25528
                 URL: https://issues.apache.org/jira/browse/FLINK-25528
             Project: Flink
          Issue Type: Improvement
          Components: API / State Processor, Runtime / State Backends
            Reporter: 刘方奇


As the title, in the state-processor-api, we use the savepoint opition to 
snapshot stete 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?
