AMQP 0-9-1 brokers provide four pre-declared exchanges:

  • Direct exchange: (empty string) or amq.direct
  • Fanout exchange: amq.fanout
  • Topic exchange: amq.topic
  • Headers exchange: amq.match (and amq.headers in RabbitMQ)

Besides the exchange name and type, the following options can be used:

Options

  • :durable: If set, keeps the Exchange between restarts of the broker;
  • :auto_delete: If set, deletes the Exchange once all queues unbind from it;
  • :passive: If set, returns an error if the Exchange does not already exist;
  • :internal: If set, the exchange may not be used directly by publishers, but only when bound to other exchanges. Internal exchanges are used to construct wiring that is not visible to applications.
