gRPC does not handle application-level acknowledgement of receipt of 
messages. If you want to do this, you'll have to add it into your protocol. 
Your method might look something like this:


syntax = "proto3";

message MetricRequest {
  ...
}

message MetricResponse {
  oneof payload {
    google.protobuf.Empty ack = 1;
    ... // Whatever the original intended response was.
  }
}

service MultiGreeter {
    rpc MetricReport (MetricRequest) returns (stream MetricResponse) {}
}

Your server would then immediately acknowledge receipt of a client request 
by sending a MetricResponse with only the ack field set.
