             Summary: Expose changelog configuration in RestAPI and WebUI
                 Key: FLINK-27260
                 URL: https://issues.apache.org/jira/browse/FLINK-27260
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / REST, Runtime / Web Frontend
    Affects Versions: 1.16.0
            Reporter: Yanfei Lei


Currently, we can know whether changelog is enabled by {{state_backend}} in rest api[1], if {{state_backend }}is {{{}ChangelogStateBackend{}}}, it means changelog is enabled.

But the detailed configurations of changelog still cannot be known through rest api/web ui, this issue wants to add two fields:

{{  1. changelog_storage}}

{{  2. changelog_periodic_materialization_interval}}

into the checkpoints-config[1] response, and show these fields on web UI when changelog is enabled.
