Google did not deign to tell me, so I am looking elsewhere.
In somewhat related terms, is there a set mathematical formula for "data
skew"? Folks talk about a "little skew" or "very skewed" data.
Practically any column is going to have at least some skew, but I have
to assume that there is a threshold whereby a given histogram (ie,
insufficient number of buckets) is going to hurt your performance.
