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.
