Subject [jira] [Commented] (CASSANDRA-5357) Query cache / partition head cache
Date Wed, 29 Jan 2014 10:48:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13885215#comment-13885215

Marcus Eriksson commented on CASSANDRA-5357:
--------------------------------------------

Pushed a fixed version to https://github.com/krummas/cassandra/commits/marcuse/5357 with thrift
renaming and updates after the review in separate commits. I guess the replicate_on_write
stuff in the thrift-generated code is due to 714c423.

I'll to do the row cache -> partition cache renaming in a separate ticket.

> 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.
