Abstract
A computer running a database system receives a query. The database system services a plurality of collections. Each collection includes a plurality of workload groups. Each collection is assigned a percentage of a resource for its use. A donor collection, C, is not using its assigned percentage of the resource during a time slice tJ. The length in time of time slice tJ is less than a time in which the query is expected to execute. The query is assigned to a workload group. The assignment is determined by the computer applying a workload classification and an exception criteria to parameters of the query. The workload group is part of a donee collection, C, different from the donor collection. The donor collection donates, through the computer, use of a boost percentage of the resource to the donee collection during the time slice tJ. The boost percentage is proportional to the percentage of the resource assigned to the donee collection, the percentage of the resource assigned to the donor collection, and a Greediness Value related to the amount of the donor collection's allocated percentage of the resource available to be donated. The query is executed by the computer during time slice tJ, with the donee collection using its allocated percentage of the resource plus the boost percentage of the resource to execute the query.
