Abstract
A database system includes an optimizer to generate resource estimates regarding execution of a request in the database system, and a regulator to monitor execution of a request and to adjust a priority level of the request based on the monitored execution and based on the resource estimates provided by the optimizer. The regulator is executable to further feed back statistics regarding execution of the request to the optimizer to improve accuracy of resource estimates provided by the optimizer.
