[GitHub] [lucene] nknize opened a new pull request, #1064: LUCENE-10654: Add new ShapeDocValuesField for LatLonShape and XYShape (#1017)
nknize opened a new pull request, #1064:
URL: https://github.com/apache/lucene/pull/1064
Backport of #1017 to branch_9x
Adds new doc value field to support LatLonShape and XYShape doc values. The
implementation is inspired by ComponentTree. A binary tree of tessellated
components (point, line, or triangle) is created. This tree is then DFS
serialized to a variable compressed DataOutput buffer to keep the doc value
format as compact as possible.
DocValue queries are performed on the serialized tree using a similar component
relation logic as found in SpatialQuery for BKD indexed shapes. To make this
possible some of the relation logic is refactored to make it accessible to the
doc value query counterpart.
Note this does not support the following:
* Multi Geometries or Collections - This will be investigated by exploring
the addition of multi binary doc values.
* General Geometry Queries - This will be added in a follow on improvement.
