Google’s BigTable
Andrew’s Website has a very interesting writeup on Google's BigTable, their system for storing large amounts of data in a semi-structured manner.
> BigTable has been in development since early 2004 and has been in active use for about eight months (about February 2005). There are currently around 100 cells for services such as Print, Search History, Maps, and Orkut. Following Google's philosophy, BigTable was an in-house development designed to run on commodity hardware. BigTable allows Google to have a very small incremental cost for new services and expanded computing power (they don't have to buy a license for every machine, for example). BigTable is built atop their other services, specifically GFS, Scheduler, Lock Service, and MapReduce.
There's some audio available, too.
