• db_table: The name of the table [default: sessions]
• db_id_col: The column where to store the session id [default: sess_id]
• db_data_col: The column where to store the session data [default: sess_data]
• db_lifetime_col: The column where to store the lifetime [default: sess_lifetime]
• db_time_col: The column where to store the timestamp [default: sess_time]
• db_username: The username when lazy-connect [default: '']
• db_password: The password when lazy-connect [default: '']
• db_connection_options: An array of driver-specific connection options [default: array()]
• lock_mode: The strategy for locking, see constants [default: LOCK_TRANSACTIONAL]
