-----------------------------------------
{quote}Aside from that, have you looked at [last-value
queues|https://activemq.apache.org/artemis/docs/latest/last-value-queues.html]?
{quote}
Last-value queues is an awesome feature! Thanks for the link, I haven't looked
at that before. These queues work for my application. But I observed that
last-value queues do not remain last-value queues on broker restart. I can
confirm this from the queues information shown in the web-console, the
last-value check box is not checked after restart. May be I need to open
another issue for this if there isn't one already.
{quote}What you actually want is what I would call a "first-value queue" which
is the opposite of a last-value queue. I think a "first-value" queue would be a
better feature than a change to duplicate detection.

Yes, first-value queue would be better than changing duplicate-detection.

> Hi, duplicate cache still contains the message even if the message was
> consumed from the queue or deleted from the queue. From the documentation, it
> looks like there's no configuration to handle something like this.
> Example:
> A message containing a person's information is sent to a queue and consumed.
> After sometime, the person's address is updated and the update message is
> sent to queue. This updated message is ignored as a duplicate because the
> original message was not removed from the duplicate cache when it was
> consumed.
