In a single call, the client can only send request once, and the server can only respond once.
client.py: simple_methodserver.py: SimpleMethod -
stream-unary
In a single call, the client can transfer data to the server an arbitrary number of times, but the server can only return a response once.
client.py: client_streaming_methodserver.py: ClientStreamingMethod -
unary-stream
In a single call, the client can only transmit data to the server at one time, but the server can return the response many times.
client.py: server_streaming_methodserver.py: ServerStreamingMethod -
stream-stream
In a single call, both client and server can send and receive data to each other multiple times.
client.py: bidirectional_streaming_methodserver.py: BidirectionalStreamingMethod
