semantic web - Fastest way to load 10Gb of RDF into virtuoso triplestore? -


using

virtuoso open source edition (multi threaded) version 6.1.6.3127-pthreads of jan 14 2013 compiled linux (x86_64-pc-linux-gnu)

what fastest option load single 10gb rdf file virtuoso triple store? defaults configuration process did not finish within day.

so far gathered following options:

  1. using web interface, using db.dba.rdf_load_rdfxml_mt
  2. using 1. isql-vt console
  3. using web interface db.dba.ttlp_mt
  4. using 3. isql-vt console
  5. using "quad store upload" in conductor web interface
  6. download url

there couple of others, can found here: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/main/virtrdfinsert.

what preferred or canonical way load large amount of triples in transactional manner single file available on filesystem?

we have virtuoso rdf bulk load functions loading large amounts of rdf data, call ttlp , rdfxml_load functions under covers, allow better management of load process.

you should consider upgrading virtuoso column store release 7.1 (or later) brings significant performance improvements.
