11.2. Clojure and RabbitMQ

In this section, we’re going to write code to perform some basic communication tasks between Clojure processes over RabbitMQ. RabbitMQ uses AMQP, so having a basic understanding of it is useful in getting the most out of the system. Our first stop, then, will be to go over the essential elements of AMQP. We’ll then use the Java client library to send messages, following which we’ll write code to receive messages over RabbitMQ. Our last stop in this section will be to create a convenient abstraction over incoming RabbitMQ messages for our programs that need to process messages asynchronously.
