Hi,

I was following the RDF performance tuning tutorial on
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning

For an index created as --

"CREATE DISTINCT NO PRIMARY KEY REF COLUMN INDEX RDF_QUAD_SP
  ON DB.DBA.RDF_QUAD (S, P)
  PARTITION (S int (0hexffff00));"

What exactly does "PARTITION (S int (0hexffff00))" do? Also is the
RDF_QUAD_SP index created as a B+ tree or some other data structure?

Could someone please explain?
I checked the "create index" explanation page in Virtuoso docs, but it
didn't clarify it to me exactly.

Appreciate some help.

Thanks.
Medha
