Suppose I need to send a large amount of data from the client to the server using python gRPC. And I want to continue the rest computation when sending the message out instead of blocking the code. Is there any way can implement this?
I will illustrate the question by an example using the modified code from the greeter_client.py
for i in range(5):
res=computation()
response = stub.SayHello(helloworld_pb2.HelloRequest(data=res))
I want the computation of the next iteration continue while sending the "res" of last iteration. To this end, I have tried the "async/await", which looks like this
async with aio.insecure_channel('localhost:50051') as channel:
stub = helloworld_pb2_grpc.GreeterStub(channel)
for j in range(5):
res=computation()
response = await stub.SayHello(helloworld_pb2.HelloRequest(data=res))
But the running time is actually the same with the version without async/await. The async/await does not work. I am wondering is there anything wrong in my codes or there are other ways?
