Thanks a lot for this research, Gustav. I have been holding off any software developments and experiments until my Web server has a new motherboard and memory. Anything else major will have to wait until the winter now as my calendar is starting to fill up. ...but I will definitely flag this for further review.

Here are some useful links I found: WTF is a SuperColumn? An Intro to the Cassandra Data Model: http://arin.me/blog/wtf-is-a-supercolumn-cassandra-data-model Cassandra Jump Start For The Windows Developer: http://www.coderjournal.com/2010/03/cassandra-jump-start-for-the-windows-dev eloper/ Thrift Wiki.

Notice through the performances trials the CPU utilization remains flat! The team pushed the product to see where better utilization could be achieved and noted setting caching would help performance... But keep in mind this DBs performance is so far beyond our standard SQLs. http://jamesgolick.com/2010/4/4/two-weeks-with-cassandra.html An aside: It will be a while before the hard drive bottle-neck is really fully resolved. Right now splitting a data store across numerous drives, all indexed and cashed is the only way to lessen the performance pain. That is why the new breed of distributive databases are so fast because they manage the hardware layer so well. Our current crop of standard SQLs just leave the hardware to manage it's self.
