Interesting article, thanks. It has been a while but this is still relevant.

I was wondering: how to dispatch work into a worker thread? Let's say I have a non blocking REST method that returns an Uni object, how do I dispatch my hard disk, database, whatever intensive work into a worker thread? Do I switch to @Blocking or do I just wrap the intensive workload inside a Uni object with Uni.createFrom().item(/* workload here */)?

Perfect, that was what I was looking for!
