Adrien Grand commented on LUCENE-8928: -------------------------------------- The nightly benchmarks liked this change http://people.apache.org/~mikemccand/geobench.html - 32% faster distance filtering with Geo3D - 38% faster 10-gons filtering with Geo3D - 20% faster 10-gons filtering with shapes - 30% faster box filtering with Geo3D - 22% faster box filtering with shapes - 1% space reduction for shapes However - ~7% slower indexing for Geo3D - ~8% slower indexing for shapes > BKDWriter could make splitting decisions based on the actual range of values > ---------------------------------------------------------------------------- > > Key: LUCENE-8928 > URL: https://issues.apache.org/jira/browse/LUCENE-8928 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Priority: Minor > Time Spent: 20m > Remaining Estimate: 0h > > Currently BKDWriter assumes that splitting on one dimension has no effect on > values in other dimensions. While this may be ok for geo points, this is > usually not true for ranges (or geo shapes, which are ranges too). Maybe we > could get better indexing by re-computing the range of values on each > dimension before making the choice of the split dimension? -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
