When looking into the source code, I have a few questions: - Does the following instruction indicate that the serialization mechanism is simply changed from java serializable to protobuf?
- When creating a new serializer, it seems that mediator is also needed. Wouldn't it be duplicated? Or we only need to add the new (ProxyReliable) message type to existing DistributedPubSubMessageSerializer.scala and modify DistributedPubSubMediator? Or any brief instruction about the flow (a bit lost in the source code).
