[Haskell-cafe] data analysis question

[Tobias Pflug]

Hi,

just the other day I talked to a friend of mine who works for an online 
radio service who told me he was currently looking into how best work 
with assorted usage data: currently 250 million entries as a 12GB in a 
csv comprising of information such as which channel was tuned in for how 
long with which user agent and what not.

He accidentally ran into K and Q programming language (*1) which 
apparently work nicely for this as unfamiliar as it might seem.

This certainly is not my area of expertise at all. I was just wondering 
how some of you would suggest to approach this with Haskell. How would 
you most efficiently parse such data evaluating custom queries ?

Thanks for your time,
Tobi
