Rabbit MQ

What is Rabbit MQ?

RabbitMQ is an open-source software used as a message broker that implements the Advanced Message Queuing Protocol (AMQP). RabbitMQ provides features for routing messages between two applications and sending messages from one application to another. It is a frequently used tool to reduce the load and time of message delivery with web applications. RabbitMQ is commonly used in the case of processing long-running tasks in the background and for communication between applications, especially in the context of microservices.

Exchange

An exchange in RabbitMQ is a component used as a message router. The exchange manages how messages will be forwarded to the destination, which can be a queue or another exchange. Exchanges have several types, namely Fanout, Direct, Topic, and Headers, each of which has a different way of routing.

Routing in RabbitMQ can be done through several exchange types, namely Fanout, Direct, Topic, and Headers. The following are the routing methods for each exchange type:

1. Fanout: Fanout exchange is an exchange type that has simple routing and is independent of the message content. Messages forwarded to a fanout exchange will be directly forwarded to all queues bound to the exchange. Fanout exchanges do not use routing keys.
2. Direct: Direct exchange is a type of exchange that has more complex routing and depends on the message content. Messages forwarded to a direct exchange will be directly forwarded to the queue that has the same routing key as the message. Direct exchanges do not use wildcards.
3. Topic: Topic exchange is a type of exchange that has more complex routing and depends on the message content. Messages forwarded to a topic exchange will be forwarded to the queue that has the routing key corresponding to the message. Topic exchanges use wildcards, namely # (hash) and _ (star). # uses wildcards to match zero or more words mostly, while _ uses wildcards to match one word.
4. Headers: Headers exchange is a type of exchange that has more complex routing and depends on the message content. Messages forwarded to a headers exchange will be forwarded to a queue that has headers corresponding to the message. Headers exchange uses a binding key that corresponds to the message header.

tip

The most commonly used exchange types are Topic and Fanout.
