Hi all, I loaded geonames(40 million triples) into Fuseki and I indexed the data into lucene.
The query below takes 4 seconds to execute. While a similar SQL one into postgis takes 13 ms. PREFIX spatial: <http://jena.apache.org/spatial#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT ?place { ?place spatial:withinCircle (32.55668 -117.12865 1 "km" ) . } SQL select geonameid from geoname where ST_Intersects(the_geom, ST_Buffer(ST_SetSRID(ST_MakePoint(-117.12865, 32.55668 ),4326)::geography, 1000)::geometry) Do I need to make any extra configuration on Fuseki to improve the performance?
