I'm thinking of situations where the regeration of a cache would be very db intensive. For instance, suppose I have voting for comments, and users can filter by votes (like digg/youtube/slashdot). I set a memcache list for every filter. However when there are changes to a particular comment's vote score, the list would be invalidated. Imagine if there is a lot of voting going on, it would mean the filter lists are constantly being reloaded by the database?
