Digg says yes to NoSQL, bye to MySQL

After twitter, now is Digg who decided to replace MySQL and most of their infrastructure components and move away from LAMP to another architecture called NoSQL that is based in Casandra, an opensource project that develops a highly scalable second-generation distributed database.
