Robert Muir resolved LUCENE-7103. --------------------------------- Resolution: Fixed Fix Version/s: 6.1 master > further optimize LatLonPoint.newDistanceSort > -------------------------------------------- > > Key: LUCENE-7103 > URL: https://issues.apache.org/jira/browse/LUCENE-7103 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Robert Muir > Fix For: master, 6.1 > > Attachments: LUCENE-7103.patch > > > This comparator creates bounding boxes to avoid calling haversin(), so its no > longer a hotspot for most use cases. > But in the worst case, it could still get called many times. This could be > because the user had a massive top N value, or because the incoming data is > sorted or mostly sorted by decreasing distance, etc. > We can optimize the worst case by not invoking a full haversin, just using > something that is rank-equivalent. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
