Hi
TIA
I am trying Fuseki 2. I encountered the issue with the query timeout default
being too small for UI created datasets. I noticed that a JIRA had been raised
and closed for it but nothing has yet been released since 2.0. So I cloned the
Jena git repo and built it to produce apache-jena-fuseki-2.3.0-SNAPSHOT.zip. I
installed and configured.
I created one dataset using the UI and loaded 3m triples into it in 14 graphs.
I wanted to get a list of the graphs. Although the following query works with a
limit of 14 anything after 15 causes the error below.
Query:
SELECT distinct ?g WHERE {
graph ?g {
?s ?p ?o .
}
} limit 15
Log:
