Subject [jira] [Commented] (CASSANDRA-8897) Remove FileCacheService, instead pooling the buffers
Date Thu, 09 Apr 2015 09:43:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14487053#comment-14487053

Stefania commented on CASSANDRA-8897:
-------------------------------------

Right that makes it even easier. Once we've reached the maximum memory constraints the CLQ
will definitely not grow but should it ever shrink below the maximum at all?  I guess not.

> After CASSANDRA-8893, a RAR will be a very lightweight object and will not need caching,
so we can eliminate this cache entirely. Instead we should have a pool of buffers that are
page-aligned.
