Hi all,
I'm doing a kind of benchmarking on triple stores using DBpedia dataset,
and I'm using Jena-TDB as one of them.
I've installed Joseki server, and configured its config file to use this
dataset.
But when I try to benchmark Jena through Joseki, the performance of
Jena-TDB is very low and too many queries time out.
I've assigned 8GB of memory to Joseki.
I've also tried to query the DBpedia graph directly using
"TDBFactory.createDataset" and "QueryExecutionFactory.create", but when
I iterate through the returned "ResultSet" either with simple loop or
with "ResultSetFormatter.consume", it works only for the first few
queries and afterwards an Exception of type
"com.hp.hpl.jena.tdb.base.block.BlockException" is always thrown.
Any help will be appreciated.
