Description Justin Ross 2008-11-12 21:37:31 UTC

+++ This bug was initially created as a clone of Bug #452017 +++

Based on some message property, new messages 'overwrite' any previous message
with the same value for that property.

--- Additional comment from sergei.vorobiev on 2008-06-19 10:38:26 EDT ---

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.
