Subject [jira] [Commented] (CASSANDRA-13940) Fix stress seed multiplier
Date Sun, 08 Oct 2017 12:03:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16196081#comment-16196081

Ben Slater commented on CASSANDRA-13940:
----------------------------------------

Just got a chance to take a look at this and I agree this is a much better/cleaner implementation
than mine. Looking back at it I think the different multiplier values was only really necessary
for the very small runs that I was initially testing on but are probably too small to be particularly
relevant. I rechecked a few of my more realistic tests with the static multiplier and results
were pretty similar.

So, no objection from me to this. Maybe @tjake can review as he reviewed the initial patch?

> CASSANDRA-12744 attempted to fix a problem with partition key generation, but is generally
broken. E.G.
> {noformat}
> cassandra-stress -insert visits=fixed\(100\) revisit=uniform\(1..100\) ...
> {noformat}
> sends cassandra-stress into an infinite loop. Here's a better fix.
