Integration / RabbitMQ Interview Questions
What is an exchange in RabbitMQ?
An exchange is the component that receives messages from producers and decides which queue or queues should get a copy, based on the message's routing key, headers, and the bindings configured on it.
Every exchange has a type - direct, fanout, topic, or headers - which determines the routing algorithm it uses.
If a message does not match any binding, it is simply dropped unless an alternate exchange has been configured to catch it.
