ben-manes commented on issue #321: ACCUMULO-4641 Added loading to cache API
URL: https://github.com/apache/accumulo/pull/321#issuecomment-344053661
 
 
   We require that the user update the entry using the cache so that it can
   reevaluate the weight. That could be a put or computation. The weight is
   stored with the entry and not re-evaluated on eviction.
