Open issues in database and analytic technology

The last part of my New England Database Summit talk was on open issues in database and analytic technology. This was closely intertwined with the previous section, and also relied on a lot that I’ve posted here. So I’ll just put up a few notes on that part, with lots of linkage to prior discussion of the same points.

    An index for graphs would probably be a big materialized view that concatenates 2 or 3 or whatever edges at once. Better than nothing, but exponential in the number of hops.

    Whether real-life graphs let you store them in clever ways to get significantly better performance than that is an open question. Cogito used to claim it could, but didn’t do too much in the way of delivering.

    [...] is a potentially powerful combination, if they can effectively address the point I just made about integrating disparate latencies. That said, I’m not expecting a lot, because the CEP industry always disappoints [...]
