Dead Letter Queue
The main use of queue is that you do not need the client
and the server running at one time. Therefore, it is
possible that a message will lie in queue for long time
until the server or client picks it up. But there are
scenarios where a message is of no use after a certain
time. Therefore, these kinds of messages if not delivered
within that time span it should not be sent to the user.
Poison Queue
A poison message is a message that has exceeded the maximum
number of delivery attempts to the application. This
situation can arise when a queue-based application cannot
process a message because of errors. To meet reliability
demands, a queued application receives messages under a
transaction. Aborting the transaction in which a queued
message was received leaves the message in the queue so
that the message is retried under a new transaction. If the
problem that caused the transaction to abort is not
corrected, the receiving application can get stuck in a
loop receiving and aborting the same message until the
maximum number of delivery attempts has been exceeded and a
poison message results.
