To Andy,
I need suggestions on two issues:
(i) I launched TDB loader to upload 159.(something) million triples, it
took 357636.22 seconds to complete (!!!).
To me, TDB loader consumed an enormous amount of time because I
have 1.3 billion triples to load. In addition to
processing time, loading time is critical for me, I choose TDB
because I was impressed by the benchmark you(Andy)
published in (http://www.w3.org/wiki/LargeTripleStores). I am sure
there is a way out which I don't know but you know.
I would be really grateful if you could help me.
(*Machine* Info: I am using 64 bit machine with 8 GBntel(R)
Core(TM) i5-2400 CPU @ 3.10GHz. Its a Quad core machine
with Linux OS.)
(ii) I am using LUBM dataset and running LUBM queries. Unfortunately,
when I launch a query, the system throws a
*400 error* which essentially is bad request error. According to my
understanding, the server finds a syntactic mismatch
but I have got no idea why does it happen. I am using Fuseqi
SPARQL interface.
Thanking you in advance for your suggestions.
Regards,
Rafiq
