I think Timur is asking for a way to filter on only certain resources<br>
for quota usage/limits, like volumes in cinder or instances in nova,<br>
rather than getting back all resource usage/limits per tenant.<br>
<br>
Is that correct, Timur?<br>
<br>
While it's possible to add this, I'm not sure how much time it's<br>
actually going to save in the DB query time to get the quota information<br>
for a tenant.<br>
<br>
Anyway, it's an API change so it would require a spec for nova which<br>
means we wouldn't be getting to that until at least N since we're in<br>
spec freeze for mitaka.<br>
<br>
