> Improvements and FIxes to Stress
> --------------------------------
>                 Key: CASSANDRA-6691
>                 URL:
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Tools
>            Reporter: Benedict
>            Assignee: Benedict
>            Priority: Minor
>             Fix For: 2.1
> There were a couple of minor issues with the new stress:
> 1) The warmup period did not scale up as the cluster size increased
> 2) The mixed workload did not work with CQL
> At the same time, I have introduced a change in behaviour in the way the default column
values are generated so that they are deterministically based on the key. I have then modified
read operations to verify that the data they fetch is the same as should have been inserted,
so that stress does some degree of data quality checking at the same time. For the moment
the values generated never vary for a given key, so this does nothing to test consistency,
it only tests for corruption.
