Hi Alex,

Are you uploaded these 4GB files via WebDAV ? You might want to try the Virtuoso TTLP family of functions for uploading such large datasets as detailed at:

Hello,

I've recently been experimenting with using Virtuoso OSE as an RDF
store/SPARQL server, and seem to have things mainly set up now. I have
uploaded various N3 files to rdf_sink via WebDAV (the DBpedia store, to
be specific), and all files have succeeded except for the two largest
ones. These files are the only two over 4GB, so it would seem to be a
file size issue. Indeed, the sizes of the files when uploaded are
perfectly consistent with a 32-bit integer overflow.

My question is: is the limitation with which we have to live regarding
the Virtuoso DB/server, or is there a way to get around this? Would the
recommended solution simple be to split up the files into smaller (<
4GB) chunks?

Thanks,
Alex
