They are included to show the increae of performance using the new RPT. ---- > Spatial prefix tree based on S2 geometry > ---------------------------------------- > > Key: LUCENE-8126 > URL: https://issues.apache.org/jira/browse/LUCENE-8126 > Project: Lucene - Core > Issue Type: New Feature > Components: modules/spatial-extras > Reporter: Ignacio Vera > > Hi [~dsmiley], > I have been working on a prefix tree based on goggle S2 geometry > (https://s2geometry.io/) to be used mainly with Geo3d shapes with very > promising results, in particular for complex shapes (e.g polygons). Using > this pixelization scheme reduces the size of the index, improves the > performance of the queries and reduces the loading time for non-point shapes. > If you are ok with this contribution and before providing any code I would > like to understand what is the correct/prefered approach: > 1) Add new depency to the S2 library > (https://mvnrepository.com/artifact/io.sgr/s2-geometry-library-java). It has > Apache 2.0 license so it should be ok. > 2) Create a utility class with all methods necessary to navigate the S2 tree > and create shapes from S2 cells (basically port what we need from the library > into Lucene). > What do you think? -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
