What is Shadow redundancy? What is its use?..

Answer / puneet rana

The concept behind shadow redundancy is that a message is not deleted from the queue until the next hop has confirmed delivery to the subsequent hop. If confirmation is not received, the message is resubmitted. If the next hop server is down, the message is resubmitted to another server. Bottomline, messages are no longer lost when a routing server fails.
