An application needs to consume Messages as soon as they’re delivered.

How can an application automatically consume messages as they become available?

The application should use an Event-Driven Consumer, one that is automatically handed messages as they’re delivered on the channel.

This is also known as an asynchronous receiver, because the receiver does not have a running thread until a callback thread delivers a message. We call it an Event-Driven Consumer because the receiver acts like the message delivery is an event that triggers the receiver into action.
