Let's talk database optimizers

Whenever you write a SQL query, the database query optimizer tries to find the best possible plan to retrieve your data. The question is, what can it do and how does it do it? In this talk we will look at recent developments in query optimizers from the major database providers. With a focus on the MySQL world, we will be looking at ways to "help" the query optimizer to come up with better plans.
