Serializer is used to write structures into the db and to read them back out. Although it's unfortunate to write a custom serializer, rather than to use something pre-written, like protobuf or JSON, in order to produce precise readwrite sets which only perform state updates for keys which are actually updated (and not simply set to the same value again) custom serialization is required.
