6.6.1. Last Value Queues
Last Value Queues allow messages in the queue to be overwritten with updated versions. Messages sent to a Last Value Queue use a header key to identify themselves as a version of a message. New messages with a matching key value arriving on the queue cause any earlier message with that key to be discarded. The result is that message consumers who browse the queue receive the latest version of a message only.
