Re: [nova] Nova API call duration increases after upgrading to Caracal

Thanks Sean. Could you also point out the pull request that fixed the pinned_az field issue? So my thinking approach is 1. the duration shows obvious increment trends over time, and returns to very low after only restart nova-api. I assume it's something related to cache(?) but I couldn't understand exactly what's changed in Caracal. And I think it should only be related to nova-api itself, instead of Keystone or Placement external API calls. 2. I added driver = nova.quota.DbQuotaDriver to the [quota] section in nova.conf. It seems to make the increment a little slower(?) but could not confirm if it's something always happens. I have only tried it for once, the increment does take couple days to show obvious trends though.
