should i cache StreamObserver

[roc]

i have client and server.  i need  send data from data to server and send data from server to client . 

should i cache StreamObserver both in client and server or start a server at client machine.

I don't see any reason to start a server at client machine. Are you going to use unary calls or bi-directional streaming calls?

Assuming you are using Java, it would be helpful if you read the Client Stub and Server Stub sections in the document https://grpc.io/docs/reference/java/generated-code.html

There are also code examples in
