There is no such thing as sync vs. async API in proto definition. It's only
relevant in the generated service API. For example, given:
service HelloService {
rpc Hello(Request) returns (Response);
}
You can generate code that provides sync API, or generate code that
provides async API:
class HelloService {
public:
void Hello(const Request& request, const std::function<void(const
Response&)>& result_callback);
}
