Hello everyone,
I have a large dataset that contains about 650 millions rows. I try to
evaluate query that returns about 8000 rows. When I run this query from
command line using d2r-query function, the result is returned fast enough.
But when I evaluate the same query from Jena using
ResultSet rs = QueryExecutionFactory.create(query, RDFModel).execSelect();
it takes too long. I was waiting for several hours and then have terminated
application without waiting the end of evaluation. Why does it happen and
how to improve a runtime?
Best,
Anastasiya
