>>The load time of a 720MB CSV file containing the lineitem table from the TPC-H benchmark is below 0.6 seconds for a 600 million lines table. Yep, below one second to load a beasty dataset straight from a csv!

Wow. And I thought VFP was quick for a few hundred thousand rows!

It is definitely loading all 600m lines, or could there be a lazy load like VFP's that pulls chunks of data as required?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us.
"
-- Shakespeare: Coriolanus, Act 1, scene 1
