[jira] [Created] (LUCENE-7563) BKD index should compress unused leading bytes

Michael McCandless created LUCENE-7563:
------------------------------------------

             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.
