Title:
memorycache#get scans the whole cache for expired items on every fetch
Status in Oslo - a Library of Common OpenStack Code:
Won't Fix
Bug description:
Every time an item is fetched from the memory cache, the whole cache
is scanned for expired items:
https://github.com/openstack/nova/blob/master/nova/openstack/common/memorycache.py#L63-L67
This is not the right place to expire items - a large cache can become
slow. There should be a more sensible approach to the (difficult)
problem of cache expiry.
