We could do this later when we have several implementation of storage. However, I prefer make another API instead of ```enableChangelogStateBackend("memory")```. It's not user-friendly to make user know the storage shotcut name before using changelog, especially we may have only one storage for production in most cases. -- This is an automated message from the Apache Git Service.
