Subject: Re: [openstack-dev] DirectConsumer's mirrored queue declaration

Kei/Ray:

I recieved this response from Eugene about the mirrored queue but I just noticed it never hit the list. It was cc'd to the list but i think it was sent from an email that is not subscribed. It looks like we are fine making it mirrrored.

Hi,

Sorry, I haven't been paying much attention to the openstack-dev mailing lists lately, as I changed company.

So, on the topic: Yes, all queues, including reply queues, must be mirrored; if some aren't, that's a bug.

It was Eugene Kirpichov,

I've added him to the cc in case he is filtering the -dev mail.

What I am trying to say is, TopicConsumer's queue is declared with
{'x-ha-policy': 'all'}

We can see same declaration at FanoutConsumer, but not DirectConsumer.
As you know, rpc.call() send request through TopicConsumer, and return values  thorough DirectConsumer. So if TopicConsumer is mirrored, DirectConsumer also should be mirrored, I think.

Does anyone know who made the changes for this x-ha-policy/mirroring code in impl_kombu.py?  We want to know if leaving mirror off of the RPC reply queue was intended or an oversight?  And if intended, why?
