Google engineers have built a system that detects MySQL master failure, chooses a new master, promotes it and hooks up slaves with under a minute downtime. This is deployed in an environment where there’s zero tolerance for transaction loss of any sort. The original designer and a sysadmin who worked on the deployment will talk about design, implementation and practical lessons learned.

Very good presentation. Answers in How to do automated failover well presented. As long as you are using the google patches and are willing to stay well behind the MySQL dev curve.
