Thanks, Bryan. That sounds like a great plan to me. I'll see if I can find time to run the tests too.

> As part of ROLLUP implementation (DERBY-3002), it will be helpful to be able to measure the performance of GROUP BY.
> Using the o.a.dT.perf.clients framework, this sub-task proposes to add a GroupByClient to the performance runner
> library; the GroupByClient will run GROUP BY statements against the Wisconsin benchmark database.
