Introduction In distributed system, we widely use message middleware to exchange data between systems, and facilitate asynchronous decoupling. Now open source message middleware has a lot of time ago our own product ROCKETMQ (Metaq core) also smooth open source, get everyone's attention. So, what is the performance of message middleware? With this in doubt, our

Message ForwardingIn order for a class to understand a message, we must implement the corresponding method in code. However, at compile time, sending a message to the class that it cannot read does not give an error, because you can continue to add methods to the class at run time, so the compiler does not know in any way whether a method will be implemented in t
