[jira] [Created] (LUCENE-9737) Flexible configuration of DocValue compressions

Jaison.Bi created LUCENE-9737:
---------------------------------

             Summary: Flexible configuration of DocValue compressions
                 Key: LUCENE-9737
                 URL: https://issues.apache.org/jira/browse/LUCENE-9737
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/codecs
    Affects Versions: master (9.0)
            Reporter: Jaison.Bi


LUCENE-9211 added compression for Binary DocValues.

LUCENE-9633 added compression for Terms Dict from SortedSet/Sorted DocValues.

LUCENE-9378 makes Binary DocValues compression configurable, it introduces two modes: 
 * BEST_SPEED
 * BEST_COMPRESSION

It's simple to use...so Terms-dict compression shares the same configuration.

But some users may only want to try Terms Dict compression, since Binary DocValue compression may cause performance reduction..

So we need to make configuration flexible.
