Ignoring the silly bit about "records and data-streams" fitting in memory. Exactly!
My mother had a brilliant solution to the problem of grease stains on carpets that involved brown paper and an iron; but you don't see me trotting out here at random.
there is utterly no reason to trundle out n-digit numbers to “prove” your point.
