Subject [jira] [Commented] (CASSANDRA-4694) populate_io_cache_on_flush option should be configurable for each column family independently
Date Tue, 23 Oct 2012 15:07:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13482388#comment-13482388

Alexey Zotov commented on CASSANDRA-4694:
-----------------------------------------

I suggest to do that in different ticket to prevent future rebasing of the current code. I'll
create another ticket and assign it to me after the current ticket will be closed. Is it ok?

> I suggest to configure populate_io_cache_on_flush option for each column family. It should
be configurable from cassandra-cli and should be stored in System keyspace. 
> That could be useful if you have a few column families inside single keyspace and you
need to fit in memory only one of them.
> Patch has been attached. I've been testing it on pseudo-cluster using ccm. So I don't
have fully confidence about lack of bugs. Please carefully review that code.
