Description

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.
