You will learn to bind a Queue with a Topic Exchange using a routing key pattern. You have already learned about Exchanges and Queues in the Elements of RabbitMQ. The diagram here explains a producer sends a message to my-topic-exchange, there are 3 Queues bound to this exchange with 3 routing key patterns (health.*, #.sports.* and #.education). As you have noticed, in a topic exchange the Queues are linked using the routing key patterns instead of a simple routing key. Before understanding the message in Topic Exchange, let us understand the routing patterns.
