Name	Default	Changeable

Here's a short explanation of the configuration directives.

tokyo_tyrant.default_timeout int: Default timeout when connecting to databases
tokyo_tyrant.session_salt string: The secret that is used to salt session id
tokyo_tyrant.key_prefix string: Prefix all keys with this string. The prefix is transparent to the developer but helps making sure that keys won't collide if multiple applications are using the same database.
tokyo_tyrant.allow_failover int: Whether to allow session failover in case a server dies.
tokyo_tyrant.fail_threshold int: How many read/write or connection failures is allowed before server is marked as failed.
tokyo_tyrant.health_check_divisor int: Defines the divisor for the health check probability. If there are failed servers and the probability matches, the servers are health checked and in case the server seems healthy, it will be added back to the pool.
tokyo_tyrant.php_expiration int: Whether to use built in session expiration mechanism or delegate the expiration to a lua-script on the server-side.
