Andy Seaborne commented on JENA-1277: ------------------------------------- This has just be released in Jena 3.2.0 - can we resolve and close this now? (it can be reopened later) > Spatial Queries Very Slow For Large Databases > --------------------------------------------- > > Key: JENA-1277 > URL: https://issues.apache.org/jira/browse/JENA-1277 > Project: Apache Jena > Issue Type: Improvement > Components: Spatial > Affects Versions: Jena 3.1.1 > Environment: Linux Ubuntu > Reporter: samur araujo > Assignee: Osma Suominen > Attachments: spatial-assembler.ttl > > > I loaded geonames on Jena but the spatial queries take more than 3s to > execute. The query is below: > PREFIX spatial: <http://jena.apache.org/spatial#> > PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> > SELECT distinct ?place > { > ?place spatial:intersectBox (32.55668 -117.12865 32.56668 -117.13865) . > > } > The data can be downloaded here: > https://drive.google.com/file/d/0B-fwYPJYT1GOYVVIZF9ROUxzclk/view?usp=sharing > For small datasets the queries are executed in 200ms, very fast. I noticed > that when I access the lucene index directly the queries are also very fast, > about 20ms. > The issue may be related to the pos-processing of lucene results. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
