Hi, I want to know how the client is used. Will multiple consumers be created in the same process?
yes. in the same process. it is a rocketmq client. the process is a java application using springboot+rocketmq For example, there is a topic: hello_topic， Then there were 3000 consumers who consumed the topic according to the conditions and found that the process memory occupied 10G
Rocketmq grpc client will create a thread pool for every consumer or producer. So I modify the client source code to fix this problem。
