Subject [jira] [Commented] (CASSANDRA-3498) Add same-row contention mode to stress tool
Date Thu, 24 Nov 2011 16:29:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13156801#comment-13156801

Sylvain Lebresne commented on CASSANDRA-3498:
---------------------------------------------

I understand I'm coming a little late, but I actually remembered that for counters we've introduced
the -F option, that allows to specify how many different keys to use. In other word, stress
-n 10000 -F 1 will do 10000 insertion on the same row. Maybe that could actually be enough
for generating artificial contention ?

 (Maybe we can re-use the same pseudorandom distribution code we already have for reads.)
