Red Hat Bugzilla – Bug 452017
Last value queue
Last modified: 2009-02-04 10:35:00 EST
Based on some message property, new messages 'overwrite' any previous message
with the same value for that property.
LVQ has the same basic features as a regular queue (such as acquire modes,
transactional delivery, ability to cluster, transient vs durable etc) and some
special features, described below. Elements in the queue can be represented as
one-dimensional array, where for a given identifier /routing key?/ there is only
one message. When a new message with the same identifier arrives, it replaces a
previous message with the same identifier. Sequence of the messages in the queue
does not matter. If it was possible to retrieve a specific message from this
logical queue, based on its identifier without retrieving other queue messages,
it would be even better.

code to test this can be found:
Manually validated on RHEL 5.2 / 4.7, i386 / x86_64 on packages
qpidd-0.4.725652-2.el5 using comment #4 example code.
