After Twitter, Digg decided to say goodbye to MySQL and replaced most of its infrastructure, digg will migrate from the lamp (Linux, Apache, MySQL, PERL/PHP/Python) architecture to the Cassandra-based nosql architecture.

Apache Cassandra is an open-source distributed database management system originally developed by Facebook to store extremely large data. Cassandra is a hybrid non-relational database. It is mainly characterized by a distributed network service composed of a bunch of database nodes rather than a database, and a write operation on Cassandra, it will be copied to other nodes, and the read operations on Cassandra will also be routed to a node for reading.

Casandra users now include rackspace, Digg, Facebook, Twitter, Cisco, Mahalo, ooyala, etc.
