Hi,
Since my server function need to deal with a large amount of data, I hope that the server can work on dealing with these data when there is no client calls. Therefore, when the client call arrives, the server can return the already dealt results to the client which will be much more efficient.
That means the server does work like this:
```cpp
//server.cpp
ServerBuilder builder;
builder.AddListeningPort();
builder.RegisterService();
std::unique_ptr<grpc::Server> server(builder.BuildAndStart);
server->Wait(); // here the server blocks and wait for client calls. I need the server to execute the data dealing program when there is no client calls
```
I hope that when there is no client calls, the server can still execute some codo rather than get blocked and only wait for the client.
How could I do this please ?
