1. Looking at the swoole document, I only see the implementation of asynchronous mysql, but I don’t see the specific application. It may be that I didn’t see it. I just want to ask if I use asynchronous query mysql in a request. The asynchronous query will call callback. How should I get the query results of this callback in this request
