Hi Erick,
Can you confirm that the bitmap indexes are in place on your Virtuoso
RDF Quad store table "DB.DBA.RDF_QUAD", you can check this from the
Virtuoso Conductor by checking the indexes this table ?
The indexes we recommend be set on the table are:
create bitmap index rdf_quad_opgs on
Hi Rajeev,
I will have to inquire of development as to the internal
implementation, although you should be able to use the virtuoso
explain command with isql or the conductor interactive sql interface
to see how the command is compiled internally for execution, to see
if any optimizations
Hi Rajeev,
The inference costs are directly related to the complexity of the
inference rules. For subclass, and subproperty we haven't see
anything significant based on theYago rules applied to DBpedia
recently. Is their a specific case/instance in which you are
encountering a performance
