      Description

      Per discussion on the mailing thread:
      https://lists.apache.org/thread.html/ra178ce29088b1da362d98a5a6d8c7be48051caf1637ee24261738217%40%3Cdev.flink.apache.org%3E

      We decide to make a refined version of loading ChangelogStateBackend:

      • Define consistent override and combination policy (flag + state backend) in different config levels
      • Define explicitly the meaning of "enable flag" = true/false/unset
      • Hide ChangelogStateBackend from users
