Lo que suele suponerse

A client can receive responses larger than 4MB without additional configuration because the default 4MB limit applies only to server request payloads, or by setting grpc.MaxCallSendMsgSize on the client.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

Contrato

• When a gRPC server returns a 5MB payload to a client with default options, the server transmits it without error but the client fails to decode the response with status code ResourceExhausted because the default client-side receive limit is 4MB.
• Configuring grpc.WithDefaultCallOptions(grpc.MaxCallSendMsgSize(10*1024*1024)) on the client does not permit receiving 5MB responses and still results in ResourceExhausted.
• Configuring grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(10*1024*1024)) or passing grpc.MaxCallRecvMsgSize to Invoke allows the client to successfully receive the 5MB response.
• Sending a 5MB request from a client to a server with default options causes the server to reject the incoming message with status code ResourceExhausted unless the server is configured with grpc.MaxRecvMsgSize.
