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.
Thanks,
