Helo, With kolla ansible nano /etc/kolla/config/global.conf [oslo_messaging_rabbit] rabbit_quorum_queue = true but you need destroy (rm rabbitmq container and its volume ) and redeploy new one to make quorum queues work.

Great! This is good to know that Quorum is a good solution.
Do you have a config to enable in kolla-ansible deployment?

Hey,
We are also using quorum in some regions and plan to enable quorum everwhere.
Note that we also manage to enable quorum for transient queues (using a custom patch as it's not doable with current oslo.messaging, see my request in [1]). We also introduced some custom changes in py-amqp to handle correctly the rabbit disconnections (see [2] and [3]).
So far, the real improvment is achieved thanks to the combination of all of these changes, enabling quorum queue only was not enough for us to notice any improvment.
The downside of quorum queues is that it consume more power on the rabbit cluster: you need more IO, CPU, RAM and network bandwith for the same number of queues (see [4]). It has to be taken into account.
Cheers, Arnaud.

Hello. Firstly, when I used the classic queue and sometimes, my rabbitmq cluster was broken, the computers showed state down and I needed to restart

Hi Khôi,
Why do you say using the quorum queue is more stable than the classic queue ?
Thanks,

Hello Huettner, I have used the quorum queue since March and it is ok until now. It looks more stable than the classic queue. Some feedback to you. Thank you. Nguyen Huu Khoi.
