> The serialized key and namespace for state queries contains a magic number between the key and namespace: {{key|42|namespace}}. This was for historical reasons in order to skip deserialization of the key and namespace for our old {{RocksDBStateBackend}} which used the same format. This has now been superseded by the keygroup aware state backends and there is no point in doing this.
