Description
- 用了new Thread来执行SQL，但是SQL又由vertx的SqlClient来执行，这里是不是会有额外的线程间的context switch? 就是new Thread和vertx event loop间的context switch
- 是不是把在new Thread里运行的SQL，放到vertx vertical里运行会更加快？这样的话就没有额外开销了，都在vertx的event loop里运行

Research direction
Start by reading AsyncPgSingleRowUpdateBTest and tracing its new Thread, Vert.x SqlClient, and event-loop execution paths. Measure the current implementation and a Vert.x-based alternative, then document whether the context-switch cost changes the result and what implementation should be preferred.
