Shaping the Optimizer's Search Space
About the Webinar

In its quest for an optimal execution plan, the optimizer is jailed into a cage laid out by the SQL query and the physical database design.

As per definition, the optimizer can only find the best execution plan within this cage—not necessarily the absolutely best way to get the result. In this session, we’ll see how indexing affects this cage and learn how to shape the search space to bring the best execution plan within the optimizer’s reach.
