I am working on an architecture with a single client and multiple servers.
GRPC raises an exception if the client starts without a server present, so
I tried modifying the HelloWorld sample to wait until a call succeeds:
done = False
while not done:
try:
response = stub.SayHello(helloworld_pb2.HelloRequest(name='you'),
timeout=1)
print("Greeter client received: " + response.message)
done = True
except:
print('Waiting for server connect...')
time.sleep(1)
Strangely, though this works, it takes quite a while to connect when the
server is started after the client (about 10 seconds or more) before
showing the result. A quick internet search shows there is a WaitForReady
option in C#, but there doesn't seem to be an equivalent in Python? How
else can I check if a connection is ready?
