RabbitMQ policy to delete queues with ha-two

[lobo...@gmail.com]

Hi, I created a policy with expires=1 and pattern=.events.configurationChanged- to delete queues without consumers but it does not delete my queues.

In a local environment without high availability configured it works, but in production environment with high availability configured it does not work.

I thing the queue high availability in production is the point. How can I create a policy to delete queues in a high environment?

Thanks.

Márcio.

Did you add this to the policy which enables mirroring or as a separate policy?

Only one policy is active at the time:

Also, classic queue mirroring (HA policies) will be removed in RabbitMQ 4.0 next year. Use quorum queues if you need replication.

Thanks for reply.
I created a separate policy for exparies, now It works, because my ha-two policy has priority "0" and my new policy to delete queues without consumers a set priority "999", then it worked. But my cluster was down and it was hard to delete the exparies policy. After a few tries the exparies policy was deleted and the ha-two policy was aplied again by RabbitMQ and after 30 minutes the 3 cluster nodes was up again and all works.
But how is the best way to do this, without down the cluster?

I don't understand why your cluster was down. Either way, the best way is not to use queue mirroring.
