Stefania commented on CASSANDRA-13773: -------------------------------------- I've started the dtests on our internal CI, if there is a way to run them on CircleCI please launch them and I haven't set it up yet. I've tested a bit locally as well, and I think we are better off skipping the command entirely when {{n=0}}, not just the warm-up, otherwise {{cassandra-stress write n=0}} (with no rate specified) will loop over different rates and sleep for no good reason whatsoever. So I suggest that we create the schema and then exit, see [here|https://github.com/apache/cassandra/compare/trunk...stef1927:13773-3.0#diff-fd2f2d2364937fcb1c0d73c8314f1418R57]. > cassandra-stress writes even data when n=0 > ------------------------------------------ > > Key: CASSANDRA-13773 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13773 > Project: Cassandra > Issue Type: Bug > Components: Stress > Reporter: Eduard Tudenhoefner > Assignee: Eduard Tudenhoefner > Priority: Minor > Fix For: 3.0.15 > > > This is very unintuitive as > {code} > cassandra-stress write n=0 -rate threads=1 > {code} > will do inserts even with *n=0*.
