RE: triple (quad) storage sizing

William


The Virtuoso column store will be a part of VOS. The cluster edition will be
commercial-only, as up to now.   On the SQL side one can choose whether a
table/index will be stored row-wise or column-wise.  With RDF, the quads
will be likewise represented either as a row-wise or column-wise table.
Columns are a lot more compact and usually offer better performance even if
the row-wise representation too did fit in RAM.

I see, I was perhaps misled by http://lod2.eu/Deliverable/D2.3.html

Still curious, will this be part of VOS?
