> We currently have the change logger embedded within the RocksDB store implementations, however this results in multiple implementations of the same thing and bad separation of concerns. We should create new LoggedStore that wraps the outer most store when logging is enabled, for example:
> loggedStore -> cachingStore -> meteredStore -> innerStore
