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 - there should be a periodic task to take care of expired items. |

This is not the right place to expire items - a large cache can become slow. There should be a periodic task to take care of expired items. |

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. |
