compressions
[ https://issues.apache.org/jira/browse/LUCENE-9737?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jaison.Bi updated LUCENE-9737:
------------------------------
Summary: Flexible configuration for DocValue compressions (was: Flexible configuration of DocValue compressions)
> Flexible configuration for 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
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> LUCENE-9211 added compression for Binary DocValues.
> LUCENE-9663 added compression for Terms Dict from SortedSet/Sorted DocValues.
> LUCENE-9378 made Binary DocValues compression configurable, it introduced two modes for DocValues(Similar with the two modes from Lucene87StoredFieldsFormat):
> * 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.
