Delay Queues

Delay queues provide an initial period of invisibility for messages. Predefine periods can ensure that processing of messages doesn't begin until this period has expired.

Dead-Letter Queues

Dead letter queues allow for messages which are causing repeated processing errors to be moved into a dead letter queue

in this queue, different processing methods, diagnostic methods or logging methods can be used to identity message faults
