Hi all,
We run AMQ 2.39.0 with NFS shared-store ha-policy.
NFS Service is based on Hitachi HNAS Cluster. When NFS Share is moved online to
the other site, our AMQ Backup takes over and Primary is terminating.
Is there a way to remain Primary "warm standby" without terminating the process

For pub/sub use-cases (which I believe is what is in view here) Artemis

Hi William-
A messaging pattern of millions of queues with low volume of messages sounds
like an anti-pattern.
Keep in mind that there is overhead for maintaining a queue — indexes, etc —
and you’d need a consumer object per-queue residing in the broker. If you add
networking-of-brokers to tha
It really depends on your specific use-case. I'd recommend you consult with
the Apache Kafka community if you're interested in exploring options in
that direction. There's likely not many (if any) Kafka experts on this list.

Justin,
Never, I think I found it:
“…the web console's behavior is configurable. Go to the "Preferences"
(available from the menu in the top right) and click the "Jolokia" tab. Here
you can turn off auto-refresh (i.e. "Update rate"). You can also decrease the
amount of data fetched by lowering
Justin,
Appreciate your reply. Your insight is greatly appreciated and invaluable.
If you can provide more details on this, then I would appreciate it. I can
search the archives for it as well. I am guessing there is some command line
equivalent to represent the tree.

I can't recall any particular changes here. Did you create your instance of
2.39.0 from scratch or did you upgrade it from 2.30.0?

The broker itself doesn't impose any arbitrary limits on the number of
addresses & queues. That said, there certainly are limits, the size of your
heap probably being the most important. Every address and queue carry with
it some memory overhead including the objects themselves but also related

Alexander,
Thanks for your reply. Are you using the G1GC garbage collector or something
else?
Are you using durable or non-durable queues?

Hi William,
I have performed a small test: created 1 queues using bash script which
calls Joloka API using curl in a loop. It works a bit slow because each API
call needs to perform an authentication and to create a session.
Another method is to auto-create queues when attempting to consume or

Good afternoon,
Are there any limitations or concerns with creating millions of topics and
queues within Apache Artemis that have low volumes of messages in each topic
and queue? I do not think there are as I believe Artemis should be able to
handle this use case. Important question is: Is it
