Hi Hugh,
the problem is that the jena code is blocking while executing whereas
the rdf4j code is non blocking and does allow multiple simultaneous
queries.
So I'm looking for a non blocking jena solution. Is there any ?
Best,
Jenrik

Hi Henrik,
The jena code can be simplified to the following to give an equivalent
execution to rdf4j:
String query = "select .....";
VirtuosoQueryExecution vqe = VirtuosoQueryExecutionFactory.create(query,
virtGraph);
Best Regards

Hi,
what is a comaparable jena provider query to this rdf4j provider query ?
TupleQuery tupleQuery =
connection.prepareTupleQuery(QueryLanguage.SPARQL, query);
I want to use the jena provider instead and I'm using this threaded so
it must be connection based.
My current jena implementation is using something like this :
Query sparql = QueryFactory.create(query);
VirtuosoQueryExecution vqe =
VirtuosoQueryExecutionFactory.create(sparql, virtGraph);
This will block the port (1111) until completed whereas the rdf4j code
can handle multiple parallel queries.
Best,
Henrik
