Subject [jira] [Commented] (CASSANDRA-4399) use data size ratio in liveRatio instead of live size : serialized throughput
Date Mon, 02 Jul 2012 08:31:49 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404938#comment-13404938
] 

Sylvain Lebresne commented on CASSANDRA-4399:
---------------------------------------------

We'll need to reinitialize sizeDelta to 0 in the do-loop in AtomicSortedColumns.addAllColumns
otherwise we'll report buggy numbers when there is contention.

Otherwise lgtm, except maybe that we might want to add in the comment on ISortedColumns.addAll()
that the returned long is a delta and is not always defined correctly (I am not a fan  how
having the return value not always be a valid value but I guess it might a necessary evil
for performance).
