[jira] [Commented] (CASSANDRA-5357) Query cache / partition head cache

["Robert Coli (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-5357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14138291#comment-14138291 ] 

Robert Coli commented on CASSANDRA-5357:
----------------------------------------

[~krummas] : To be 100% clear, this keeps the "invalidate on write" behavior from the previous Row Cache? 

(Your previous answer to [~d-_-b] implies so, but people reading this ticket might still be unclear.)

> I think that most people expect the row cache to act like a query cache, because that's a reasonable model.  Caching the entire partition is, in retrospect, not really reasonable, so it's not surprising that it catches people off guard, especially given the confusion we've inflicted on ourselves as to what a "row" constitutes.
> I propose replacing it with a true query cache.
