For those who didn't see it on slashdot: http://www.acmqueue.org/modules.php?name=Content&pa=showpage&pid=293 What's interesting is that PostgreSQL is already working on some of these things. Of note, there's a patch to allow sequential scans to 'piggyback' on top of other sequential scans. See the quote "For petabyte-scale databases, the only solution may be to run continuous data scans, with queries piggybacked on top of the scans." on page 4. There's also been discussion about how to more intelligently cost UDF's, something also mentioned on page 4. -- Jim C.
