> 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.
