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 ?
