Nerval's Lobster writes "Facebook recently invited a handful of employers into its headquarters for a more in-depth look at how it handles its flood of data. Part of that involves the social network's upcoming 'Project Prism,' which will allow Facebook to maintain data in multiple data centers around the globe while allowing company engineers to maintain a holistic view of it, thanks to tools such as automatic replication. That added flexibility could help Facebook as it attempts to wrangle an ever-increasing amount of data. 'It allows us to physically separate this massive warehouse of data but still maintain a single logical view of all of it,' is how Wired quotes Jay Parikh, Facebook's vice president of engineering, as explaining the system to reports. 'We can move the warehouses around, depending on cost or performance or technology.' Facebook has another project, known as Corona, which makes its Apache Hadoop clusters less crash-prone while increasing the number of tasks that can be run on the infrastructure."
