Description

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 This has now been superseded by the keygroup aware state backends and there is no point in doing this.
