CREATE SQL statement optimization

[hohl]

You can reduce the recommended DB table setup (at README.md):

CREATE TABLE IF NOT EXISTS `sessions` (
  `id` varchar(32) NOT NULL,
  `timestamp` int(10) unsigned DEFAULT NULL,
  `data` mediumtext,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Also needs index on timestamp.
