Vert.x Notes

Vert.x Core

Golden Rule: Don’t block the event loop.

• Don’t call us, we call you
• In most cases Vert.x calls your handlers using a thread called an event loop.
• Verticles
• Asynchronous coordination
• Verticle is a bit like an actor in the Actor Model.(Different verticle communicate with each other by sending messages on the event bus.)
• The Context Object (Usually a context is an event-loop context and is tied to a specific event loop thread.)
