--------------------------------------------------------------------

There is going to be some tradeoff of flexibility and simplicity here.  Coming from scratch
with no understanding of how the tool works, it's very easy to shoot yourself in the foot.
I feel like the having well documented recipes of different profiles is the best way to go.

Also [~sebastian.estevez@datastax.com] has built a nice UI for visualizing schemas and distributions
which maybe we could take a look at http://www.sestevez.com/sestevez/CASTableSizer/

> Some of the trouble people have with stress is a documentation problem, but some is functional.
> Comments from [~iamaleksey]:
> # 3 clustering columns, make a million cells in a single partition, should be simple,
but it's not. have to tweak 'clustering' on the three columns just right to make stress work
at all. w/ some values it'd just gets stuck forever computing batches
> # for others, it generates huge, megabyte-size batches, utterly disrespecting 'select'
clause in 'insert'
> #  I want a sequential generator too, to be able to predict deterministic result sets.
uniform() only gets you so far
> # impossible to simulate a time series workload
