Subject [jira] [Commented] (CASSANDRA-5455) Remove PBSPredictor
Date Thu, 16 May 2013 05:17:16 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13659231#comment-13659231
] 

Jonathan Ellis commented on CASSANDRA-5455:
-------------------------------------------

I'd prefer option 1 but I'm also fine with option 3.

For option 1 we do need to distinguish between "track latency stuff on a per-CF basis" (which
is universally useful as, say, an EstimatedHistogram) and "keep a window of individual latency
times" which is pretty much only a PBS requirement.  As I said above, we'd want to keep the
latter disabled unless specified otherwise.

> It was a fun experiment, but it's unmaintained and the bar to understanding what is going
on is high.  Case in point: PBSTest has been failing intermittently for some time now, possibly
even since it was created.  Or possibly not and it was a regression from a refactoring we
did.  Who knows?
