AFAIK if a message can't be routed there are three options: - the message is discarded (I think this is the default option) - the message is sent back to the publisher (some params need to be specified when a message is published) - some broker can have specific queues for those messages, for example Rabbitmq has a "dead letter queue" where not routable messages are stored. Durable exchanges are exchanges that survive to a server restart, they don't need to be re-declared.
