[jira] [Commented] (CASSANDRA-6878) Test different setra values in
EC2 to find the best performance
[ https://issues.apache.org/jira/browse/CASSANDRA-6878?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16287094#comment-16287094 ]
Jeff Jirsa commented on CASSANDRA-6878:
---------------------------------------
This is going to end up being very data and hardware dependent - what do we do with the recommendation? We can't build it into a script, because we don't know what data looks like. Do you feel strongly that this needs to happen? It's been 3 years and no movement, I propose we won't-fix it unless you really believe it's useful.
