Teradata Virtual Storage

One of the big features of Teradata 13.0, announced this week (Edit: and to be shipped some time in 2009), is Teradata Virtual Storage, which sounds pretty cool. So far as I can tell, Teradata Virtual Storage has two major aspects, namely:

I’m squirming a little bit at that fully automatic aspect, for two reasons. First, there’s the delay in moving new data to the hot areas. Of course, a simple workaround for that problem is for data to start out in high-speed “hot” areas, and only get moved to cooler ones if it’s not much used.

My second reason for squirming is that all systems exhibit pathological behavior from time to time, and it’s comforting to be able to override that, and I don’t know what kinds of manual override Teradata offers. I’ll see if I can get some answers before leaving Las Vegas.
