Seth Wiesman commented on FLINK-25528: -------------------------------------- The state processor api only takes a single snapshot at end of input. Even if we used incremental snapshots it would still be the entire state backend. > 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 > 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? -- This message was sent by Atlassian Jira (v8.20.1#820001)
