Before working through the configuration of an ontology model in
fuseki2, I wanted to ask if anyone has experience with large models.
I estimate there will be 250K class definitions, about 40M triples.
That's not that large :-)
(There are installations I've worked with x10 that many triples).
What hardware are you running on?
My queries will be for instance checking:
select ?class
where {
_:a rdf:type ?class;
ex:p1 "v1";
ex:p2 <R1>;
Well, depending on the frequencies of
? ex:p1 "v1"
and
? ex:p2 <R1>
that query will be quite fast. i.e. if there is a property-object that
selects a few resources (100s), then that 's no much of a stress test
should work fine.
# ...all properties of _:a
.
}
Is there hope of fast performance in this scenario?
Yes.
Any other approaches for better performance?
Thanks,
