it has a pretty big performance penalty if combined with durable queue<br>
and in generall its questionable if it should be used going forward.<br>
<br>
there is an argument to be made that ha/mirrored queues and durable queue shoudl be replaced<br>
with <a href="https://www.rabbitmq.com/quorum-queues.html" rel="noreferrer" target="_blank">https://www.rabbitmq.com/quorum-queues.html</a><br>
<br>
<br>
the other thing to consider is that this needs to eb set per vhost<br>
so if two serivce share a vhost it needs to be set to the same value.<br>
<br>
in general for notificaiton both ha and durable queues shoudl be disabled as notifcation are intented<br>
to be fire and forget<br>
for rpc calls or casts having relibale deliver is imporant but how you acive that is archittur dependent.<br>
meaning using ha queue is not alwasy the corrct default.<br>
if you need to scale to many request per secodn you are better off using durable queuse with storge on something like<br>
ceph/nfs and an active/backup deployment with one rabbit per openstack service. you might choose to run such a rabbit<br>
cluster in a k8s env for example using persitent voluems.<br>
<br>
in other cases simple ha queues and a shred rabbit is fine for small scale deployments.<br>
quorum queue may also make more sense.<br>
<br>
this is why rabbit is called out in the production arctechture guide<br>
<a href="https://docs.openstack.org/kolla-ansible/latest/admin/production-architecture-guide.html#other-core-services" rel="noreferrer" target="_blank">https://docs.openstack.org/kolla-ansible/latest/admin/production-architecture-guide.html#other-core-services</a><br>
and why there is an option to opt into ha/durable queues since that is often enough for small scale deployments.<br>
