statehandling of MMORGS to handling of huge numbers of inputs from a million sensors in real time, and providing
reportingdata on these).

Yeah, same with me. I use PG as both OLTP and data warehouse. My problems are not facebook problems, and PG
transactionrate is much faster than I need (now or in the foreseeable future).
I could not really use voltdb because I'd like to have a very long history (5 gig and counting). In his little
triangleI sit pretty squarely in the middle. I want some OLTP and some warehouse, and PG is fast enough at both.
I just watched the video about CERN (also in the usenix list alonside Stonebreakers), and they describe their DB usage,
wherethey collect 4 billion rows of history, a day, on the heat and alignment of magnets. VoltDB wont work there
either.(As Mike himself says, its not for warehousing, don't use it as such)
I'm just saying these are different tools for different jobs. Your in memory tables wont help me, I dont really want
them. I'd rather have core development time on other things.
Its just like different programming languages... use the right tool for the right job.
