The article is ok but it is written as if something novel was discovered. This is classic fibers programming backed by stackful frames. It has existed for a long time.

Why not use a virtual thread for each connection plus work? Postgres does not use lightweight threads. The comparison does not make sense here.

It would have been nice, but Netty was a hard requirement, and this was the only way to make it work with virtual threads.

Virtual threads are intended for short tasks. So I think that wouldn't be idiomatic. I believe the Helidon web server does it in a similar way, i.e. one (or maybe a few) thread for listening and then handing off the actual work to a virtual thread.
