When and why to use RabbitMQ?
RabbitMQ
  • RabbitMQ is an AMQP (Advanced Messaging Queuing Protocol) message broker.
  • It supports multiple messaging protocols, message queuing, delivery acknow led gement, flexible routing to queues and multiple exchange types
  • RabbitMQ can be deployed with Docker, Puppet, Chef and BOSH
  • RabbitMQ can be deployed as clusters for high availa bility and can be federated across multiple availa bility zones and regions
Protocol Support
  • AMQP - It is a default implementation in RabbitMQ
  • MQTT - Used for light scenarios. Binary exchange.
  • STOMP - Text-based data exchange
  • HTTP - Our very popular internet protocol
  • While Kafka supports Binary protocol over TCP.
Key Terms
  • Producer - a programm that sends messages.
  • Consumer - a programm that reads messages.
  • Publishers
  • Exchange - takes a message from producers and routes it into zero or more queues.
  • Routes
  • Queue - a buffer that stores messages.
  • Topics
  • Subscribers
  • Bindings - rules that exchanges use to route messages to queues.
Exchange types
  • default - exchange with no name pre-declared by the broker. Every queue that is created is automatically bound to it with a routing key which is the same as the queue name.
  • direct - delivers messages to queues based on the message routing key. It?s ideal for the unicast routing of messages. It?s often used to distribute tasks between multiple workers.
  • topic - routes messages to one or many queues based on matching between a message routing key and the pattern that was used to bind a queue to an exchange. The limitation for routing key is 255 bytes.
  • fanout - routes messages to all of the queues that are bound to it and the routing key is ignored
  • headers- routes multiple attributes that are more easily expressed as message headers than a routing key. routing key is ignored.
