A computer running a database system receives one or more queries, each query comprised of parallel threads of execution working towards the common goal of completing a user request. These threads are grouped into a schedulable object called a task group. The task groups are placed within a specific multiple tier hierarchy, and database system resources allocated to the task groups according to their placement within the hierarchy. Beginning with the top tier of the hierarchy, resources remaining after allocations to each task group within a tier are passed to the next lower tier for allocation.
