Abstract
A workload management service component of a parallel database-management system monitors usage of computational resources in the parallel database-management system. The component provides a query-processing-task-management interface and a query-execution engine. The engine receives query-processing requests associated with one of a number of services from host computers, and accesses the workload-management-services component to determine whether to immediately launch execution of query-processing tasks corresponding to the received query-processing requests. Alternatively, the engine accesses the component to place the query-processing requests on wait queues for subsequent execution. The determination is based on the current usage of computational resources within the parallel database-management system.
