摘要： A system, for example, an online system or a database system schedules requests received for execution. The system maintains consumer groups and receives a measure of amount of resources allocated for each consumer group. The system maintains a measure of accumulated elapsed time of execution of requests received from each consumer group. If the system determines that resources are available for executing a request, the system selects a request for execution from a consumer group based on the measure of accumulated elapsed time for processing queries for the consumer group and the measure of amount of resources allocated for the consumer group. The system maintains relative cumulative elapsed times of queries across consumer groups in the same ratio as the allocated share for the consumer groups. Accordingly, the system schedules requests such that each consumer group approaches its allocation of resources compared to other groups smoothly over time.
