- I think we should change the term identity to population as it seems clearer
to me for the columnspec. and in the code identityDistribution to
populationDistribution
- I'm not sure how I feel about putting the batchsize and batchtype into the
yaml. Those feel like command line args to me.
- It sounds like writing to an entire partition at once is a step backwards
from the original patch, since you can't test writing incrementally to a wide
row. all clustering columns are written at once (unless I'm misunderstanding).
Previously the population distribution of a column was not within a partition
so you could make it very large.

> The existing CQL "support" in stress is not worth discussing. We need to
> start over, and we might as well kill two birds with one stone and move to
> the native protocol while we're at it.
