Alan Woodward commented on LUCENE-7774:
---------------------------------------
I started to play with a patch for this, but it turns out to be a bit tricky,
as the BKDWriter is an implementation detail of the Lucene60PointsWriter, and
we don't have an easy way to pass configuration parameters to Codecs. So this
is mainly a discussion JIRA at the moment. [~mikemccand] do you have any
thoughts?
> Allow BKDWriter buffer sizes to be configurable

> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Alan Woodward

> 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.
