Eventmachine talk - Oct 2006 - OT: message queue dead letter queue

I''m working some more on stompserver, but not having used MQ software
that much I''m not really sure of the best way to implement the dead
letter queue.  At the moment if something goes wrong and a message
can''t be delivered, I create a queue called  original_queuename.dlq
and enqueue the aborted message there.  So if a message being consumed
from /queue/test isn''t delivered for some reason, it gets enqueued to
/queue/test.dlq.

Comments?

I''m missing something. Is stompserver an effort  to integrate with
ActiveMQ?
And doesn''t AMQ have its own ideas abou dead letter queues?

stompserver is a simple mq server for stomp.  It would be used in
place of activemq if you don''t need all the activemq features like
distributed brokers.

MQ systems often have a systemwide dead letter queue. One that I wrote once
did it more like your suggestion, by leaving messages in queues but with a
selectable "exception" flag after one or more unsuccessful delivery
attempts.
