Description Daniel Kinzler 2013-06-27 17:33:05 UTC 
We use memcached for several things ()full entities, property labels, soon property data types, etc). The memcached entries are shared between wikis.

To avoid conflicts when a) multiple repos exist or b) different versions of the software are in use, the wiki ID of the repo and the version ID of the software making the entry should be included in the cache key.
Comment 1 Aude 2013-06-27 18:16:53 UTC 
wiki id of the repo is definitely needed.

at some point soon, we'll want test2 to use test.wikidata as it's repo. In that case, we definitely don't want wikipedias to share memcached data with test2 and serve test data to the wikipedias!
