------------------------------------------
Summary: BKD index should compress unused leading bytes
Key: LUCENE-7563
URL: https://issues.apache.org/jira/browse/LUCENE-7563
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Fix For: master (7.0), 6.4
Today the BKD (points) in-heap index always uses {{dimensionNumBytes}} per
dimension, but if e.g. you are indexing {{LongPoint}} yet only use the bottom
two bytes in a given segment, we shouldn't store all those leading 0s in the
index.
