Subject [jira] [Resolved] (SOLR-3830) Rename LFUCache to FastLFUCache
Date Wed, 12 Sep 2012 20:11:08 GMT

     [ https://issues.apache.org/jira/browse/SOLR-3830?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adrien Grand resolved SOLR-3830.
--------------------------------

    Resolution: Won't Fix

Given that we can neither rename LFUCache to FastLFUCache nor rename FastLRUCache to something
else, I am marking this issue as won't fix since there is no way to have a consistent name
for these two classes.

> 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.
