Oracle *can* handle petabytes of data but I bet it would be cheaper to
clone BigTable than to fork over the kind of cash Oracle would demand.
Unfortunately, Hbase doesn't look to be very far along so you'd pretty
much be on your own.
(Of course BigTable isn't relational... but it scales a hell of a lot
better for what it does.)
