Description
BKDWriter has a 16Mb internal buffer it uses for sorting points, which then spills over to on-disk sorting if there are too many values. The difference in performance between in-buffer and on-disk sorting is pretty stark, and it would be nice to make this buffer size configurable so that users can choose to use more RAM during indexing to speed things up.
