Hello,
what is the fastest way to query for a list of graphs in the store
for the V5 and V6 series. I do not succeed to write a query that is
faster than 10 seconds.
I'm testing it on http://db0.aksw.org:8890/sparql , the latest VOS 6 ,
which has DBpedia loaded and some OntoWiki graphs.
I even tried this:
SELECT DISTINCT ?graph WHERE { GRAPH ?graph {?s rdf:type ?o}}
and it still needs almost 10 seconds, even if I call it very often,
hoping for the cache to kick in ...
Also a SQL query would be fine, but it needs to be fast
(it should be fast normally < 20ms )
It's for OntoWiki, so we also need a fast solution for the V5 series,
to be backward compatible.
Regards,
Sebastian
Expected result:
