   Table 1. Parameters

   Parameter	Description	Usage notes
   Queue Name	The queue name.	The name can contain letters, digits, hyphens (-), underscores (_), periods (.), number signs (#), forward slashes (/), and at signs (@). The name must be 1 to 255 characters in length. After a queue is created, you cannot change its name. If you want to change the name of a queue, delete the queue and create another queue. amq. is a reserved field and cannot be used as the prefix of an exchange name. For example, you cannot use amq.test as the name of an exchange.
   Auto Delete	Specifies whether the queue is automatically deleted after the last subscription from consumers to the queue is canceled.	true: The queue is automatically deleted after the last subscription from consumers to this queue is canceled. false: The queue is not automatically deleted after the last subscription from consumers to this queue is canceled.
   Advanced Settings	Other parameters for the queue, such as the dead-letter exchange, dead-letter routing key, and message time-to-live (TTL).	DeadLetterExchange: the exchange to which dead-letter messages are delivered. DeadLetterRoutingKey: the routing key of dead-letter messages. A dead-letter exchange sends dead-letter messages to the queue whose routing key matches the routing key of the dead-letter messages. MessageTTL: the message TTL, in milliseconds. A message that is not consumed within the specified message TTL is a dead-letter message and is sent to a dead-letter exchange. For more information, see Message TTL.
