Subject [jira] [Created] (SOLR-3830) Rename LFUCache to FastLFUCache
Date Wed, 12 Sep 2012 15:07:07 GMT
Adrien Grand created SOLR-3830:
----------------------------------

             Summary: Rename LFUCache to FastLFUCache
                 Key: SOLR-3830
                 URL: https://issues.apache.org/jira/browse/SOLR-3830
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.0-BETA
            Reporter: Adrien Grand
            Priority: Minor


I find it a little disturbing that LFUCache shares most of its behavior (not strictly bounded
size, good at concurrent reads, slow at writes unless eviction is performed in a separate
thread) with FastLRUCache while it sounds like it is the LFU equivalent of LRUCache (strictly
bounded size, synchronized reads, fast writes) so I'd like to rename it to FastLFUCache.

Maybe we should also rename these Fast*Cache to Concurrent*Cache so that people don't think
that they are better than their non Fast alternatives in every way.
