Ignacio Vera created LUCENE-8703:
------------------------------------
Summary: Build point writers only when needed on the BKD tree
Key: LUCENE-8703
URL: https://issues.apache.org/jira/browse/LUCENE-8703
Project: Lucene - Core
Issue Type: Improvement
Reporter: Ignacio Vera
With the introduction of LUCENE-8699, I have realised the BKD tree uses quite a
lot of heap even when it is not needed, for example for 1D points.
In this issue I propose to create point writers only when needed. In addition I
propose to create PointWriters based on the estimated point count given in the
constructor.
