— And if you use the Sync method of it, please use try-catch
std::this_thread::sleep_for(3s);

— U shall be judged for this!
— Which means there should be a way to know when conn is done, maybe a callback since it's a non-blocking method.
— Almost all methods in drogon are non-blocking.

— Or an bool connected() DbClient member function .
— Oh, I get the last part.
— But the interface is quite strange compared to http etc.
— Thanks, I'll think about this.
