I have been reading about MonetDB for a few days now, and have played around with it some and it seems to solve some of the ultra complex queries that I'd like to do in a time that is amazing. Congrats! One thing, though, that confuses me is some scaling issues. The data set that I'm looking at is potentially in the billions of traditional rows, with about 50 columns, so from my understanding that'd be 50 different BATs each with a billion or more items. My concern is that OIDs seem to be restricted to 2^32-1, although from looking at virtual OIDs, it's unclear whether in my situation that would be useful? Any thoughts on stuffing that much data into the system, especially how it might impact dealing with VM issues? I'm more than happy to say "this is the wrong approach" or system for this problem, as this is obviously a non-normal case. Chris -- | Christopher Petrilli | petrilli@gmail.com
