I assume they have both a budget and competent management that will let them get away with something like the Lambda architecture. I reckon it's a lot harder to scale to even a terabyte under the constraints of a grubby setting like a datawarehouse for some instrument monitoring company. Those guys will allow at best MS SQL for storage, and won't mind putting their developers through hell.
