MySQLConf 09: This is Not a Web App: The Evolution of a MySQL Deployment at Google

Posted in Companies, Conferences, Databases on April 28, 2009

What happens after you launch a product that depends on MySQL and the product becomes successful? Suddenly everyone expects much more from the MySQL deployment and everyone includes database users, bosses, auditors and the general public. I will describe the work we have done to meet these expectations from 2006 until today. The work continues as problems change, new problems arrive and our understanding of the system improves.
