--------------------------------------
Summary: Switch GeoPointTermsEnum range list to use a reusable
BytesRef
Key: LUCENE-6777
URL: https://issues.apache.org/jira/browse/LUCENE-6777
Project: Lucene - Core
Issue Type: Improvement
Reporter: Nicholas Knize
GeoPointTermsEnum currently constructs a BytesRef for every computed range,
then sorts on this BytesRef. This adds an unnecessary memory overhead since
the TermsEnum only requires BytesRef on calls to nextSeekTerm and accept and
the ranges only need to be sorted by their long representation. This issue adds
the following two improvements:
1. Lazily compute the BytesRef on demand only when its needed
2. Add a single, transient BytesRef to GeoPointTermsEnum
This will further cut back on heap usage when constructing ranges across every
segment.
