[jira] Commented: (CASSANDRA-860) Option to populate the row cache on writes as well as reads

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12928814#action_12928814 ] 

Jonathan Ellis commented on CASSANDRA-860:
------------------------------------------

I don't think it's a good idea to add more complexity here.  If it's really a hot row it will be pulled in by the first read; doing that optimistically is no better (because we can't assume we're having the entire row written, we need to hit the read path) and often will be worse (when it really isn't hotter than what it's displacing).
