commit 42eda48c78f1153081b4c193dc13c88561409fd3 Author: David Stanek <[email protected]> Date: Mon Aug 1 21:06:50 2016 +0000 Distributed cache namespace to invalidate regions dogpile.cache's region invalidation is not designed to work across processes. This patch enables distributed invalidation of keys in a region. Instead of using a static cache key, we use the original cache key and append a dynamic value to it. This value is looked up in memcached using the region name as a key. So anytime the value of the region key changes the cache keys in that region are effectively invalidated. Closes-Bug: #1590779 Change-Id: Ib80d41d43ef815b37282d72ad68e7aa8e1ff354e ** Changed in: keystone Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Identity (keystone). https://bugs.launchpad.net/bugs/1590779 Title: Cache region invalidation works for local CacheRegion object only Status in OpenStack Identity (keystone): Fix Released Status in oslo.cache: In Progress Bug description: oslo_cache uses dogpile.cache's CacheRegion which invalidates by setting region object attributes: - self._hard_invalidated - self._soft_invalidated Then it checks these attributes on value get. So this invalidation works for particular region object only. If there is a need to invalidate a region so that values in it are no more valid for other instances of CacheRegion (either in the same process or in another one) - it's simply impossible.
