When building an application with Eclipse Vert.x, it's very common to want to perform an action
after a delay or periodically. Because of the non-blocking aspect of Vert.x, you can't make the thread sleep to
introduce a delay. It would block the event loop and that's forbidden. Instead use Vert.x timers.
In this short tutorial you learn:
How to create delayed actions using a one-shot timer,
How to schedule the periodic execution of tasks,
How to cancel timers.
It's going to take less than 10 minutes to complete, so don't delay it and give it a shoot now!
