At Cloudkick we are using Cassandra to store monitoring statistics and
running analytics over the data.  I would love to share some ideas
about how we set up our data-model, if anyone is interested.  This
isn't the right thread to do it in, but I think it would be useful to
show how we store billions of points of data in Cassandra (and maybe
get some feedback).
