Who are you people getting for DBA's? :)

And how do you propose I do that? I worked at a very very large retailer
for most of my career and they kept basically every transaction ever for
trending purposes. Now given the size of that company I would say it has to
be at least as large as Google's data (probably quite a bit bigger). Now
they didn't turn over queries in fractions of a second, but keep in mind the
general kind of queries they were dealing with. If they were limited to a
subset of possible queries like Google is, I believe they could produce
comparable times.
