LRUCache autowarmCount should support percentages
-------------------------------------------------
Key: SOLR-571
URL: https://issues.apache.org/jira/browse/SOLR-571
Project: Solr
Issue Type: Improvement
Reporter: Hoss Man
a recent thread reminded me of an old idea that never got implemented...
the autowarmCount for LRUCaches should support "percentages" which get
evaluated relative the current size of the cache when warming happens.
in this way, a Solr instance might be configured with autowarmCount="50%" to
autowarm the top half of the queries ... a master machine might be configured
this way to give some autowarming if it is inadvertently being queried, but
things won't be maintained in the caches in perpetuity ... each subsequent
cache instance would have fewer and fewer of the "old" queries warmed
automatically.
