Hi George, these are valid points. I can confirm we don't employ result caching in Brytlyt, if we did; 1) all run times would be identical regardless of query 2

Hi George, these are valid points. I can confirm we don't employ result caching in Brytlyt, if we did; 1) all run times would be identical regardless of query 2) the run times would be an order of magnitude faster I agree there is quite a bit more to a data warehouse performance than table scan speed. There are queries where scan speed is important and in the retail industry, COUNT DISTINCT is one of them. I agree the queries in this benchmark is simple, that doesn't mean they're not significant.
