  • Patent number: 10387578
    Abstract: Capacity utilization may be controlled by a token-based allocation of input/output capacity. Operations on nested objects may utilize capacity based on factors other than input/output capacity. A capacity utilization model may be used to scale input/output utilization associated with an operation on a nested object so that the scaled input/output utilization correlates to the computing capacity used performing the operation on the nested object. The correlation may be determined to be valid for a range of attributes associated with the operation.
