Hi Julie

I was looking at this myself a few weeks ago.

The manual says

Because QUANTILE uses equal-width histograms to partition the specified data, it does not partition the data equally using equal- height histograms. In other words, do not expect equal row counts per specified quantile. Expect empty quantile histograms when, for example, duplicate values for sort_expression are found in the data.


Hopefully, that answers your question.


Cheers

Paul
