Yeah, it is more like Trevor said. It is a mix of stuff. Facebook did not switch to Cassandra, they started to use it. A big difference. MySQL is still heavily used at Facebook. This article describes an issue Facebook had with MySQL replication and memcache inconsistency between their two data centers. I like how they solved the problem. They just added their own keyword to SQL that did the memcached operation they needed. http://www.facebook.com/note.php?note_id=23844338919
