Subject Message dispatching from cache
Date Thu, 10 Dec 2015 15:52:00 GMT
Hello:

I'm trying to understand how message priority works in AMQ 5.10

I'm reading

http://activemq.apache.org/how-can-i-support-priority-queues.html

and I don't understand this sentence

"Since the message cursors (and client side) implement strict ordering
of priorities, it's possible to observe strict priority ordering if
message dispatching can happen from the cache and not have to hit the
disk (i.e., your consumers are fast enough to keep up with producers)"

Is there a message cursor processing messages from cache ? Or cache is
implemented as a message cursor ?
I thought that when "your consumers are fast enough to keep up with
producers" , messages were moved directly into a dispatch queue for
the consumer

Thanks and regards
