Stefania updated CASSANDRA-13773:
---------------------------------
Resolution: Fixed
Fix Version/s: 4.0
3.11.1
Status: Resolved (was: Patch Available)
dtests looked good as well.
I don't think anyone would expect cassandra-stress to write data if n=0, so
I've committed it to 3.0 as {{6a1b1f26b7174e8c9bf86a96514ab626ce2a4117}} and
merged into 3.11 and trunk.
> 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, 3.11.1, 4.0
>
>
> This is very unintuitive as
> {code}
> cassandra-stress write n=0 -rate threads=1
> {code}
> will do inserts even with *n=0*. I guess most people won't ever run with
> *n=0* but this is a nice shortcut for creating some schema without using
> *cqlsh*
> This is happening because we're writing *50k* rows of warmup data as can be
> seen below:
> {code}
> cqlsh> select count(*) from keyspace1.standard1 ;
> count
> -------
> 50000
> (1 rows)
> {code}
> We can avoid writing warmup data using
> {code}
> cassandra-stress write n=0 no-warmup -rate threads=1
> {code}
> but I would still expect to have *0* rows written when specifying *n=0*.
