> Speed up merging segments of points with data dimensions

> Key: LUCENE-8562
> URL: https://issues.apache.org/jira/browse/LUCENE-8562
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/index
> Affects Versions: master (8.0), 7.7
> Reporter: Ignacio Vera
> Priority: Major
> Attachments: LUCENE-8562.patch, LUCENE-8562.patch, LUCENE-8562.patch,

>
>
> Currently when merging segments of points with data dimensions, all
> dimensions are sorted and carried over down the tree even though only
> indexing dimensions are needed to build the BKD tree. This is needed so leaf
> node data can be compressed by common prefix.
> But when using _MutablePointValues_, this ordering is done at the leaf level
> so we can se a similar approach from data dimensions and delay the sorting at
> leaf level. This seems to speed up indexing time as well as reduce the
> storage needed for building the index.
