Does anyone have any experience using this technology? I'd assume it works best for post processing or pseudo real time data feeds( ie within a couple of seconds as opposed to sub 20 millisecond reactions).

Where do people usually store the processed data from this system?

I can see something like this being useful for things like post trade analytics or post day analyzing the efficiency of an given algo.

We use an inhouse CEP to do this sort of work currently but I'd rather rent than buy servers for this offline processing.

By the way, if anyone is in the Toronto area and interested in working for a hedge fund my contact info is in my profile
