Hello.
I need to get a list of messages from server to client.
I see two possible ways to implement this:
1.
- define the message
- define a service with a function which returns a stream of the message
2.
- define the message
- define a second message with a repeated field of the first message
- define a service with a function which returns the second message
Here is an example:
syntax = "proto3";
import "google/protobuf/empty.proto";
message Dummy {
string foo = 1;
string bar = 2;
}
message DummyList {
repeated Dummy dummy = 1;
}
service DummyService {
rpc getDummyListWithStream(google.protobuf.Empty) returns (stream Dummy)
{}
rpc getDummyListWithRepeated(google.protobuf.Empty) returns (DummyList) {}
}
What is the most efficient way to implement this? getDummyListWithStream or
getDummyListWithRepeated?
Note: client and server are both written in C++.
Thanks.
Julien
