Jifty::Model::Session - Jifty session tracking
Every Jifty application automatically inherits this table, which tracks session information for the application. Individual keys in the session structure are stored as rows, making session updates take constant time, and also reducing the need for locking.
Sessions are stored in the table _jifty_sessions.
