      Description

      Currently, metadata is written to the state changelog using the same StateChangelogWriter.append() method as data.

      However, it doesn't belong to a specific group, and should be read first on recovery. Because of that, -1 is used.

      An explicit append() without keygroup would be less fragile (probably still using -1 under the hood).
