摘要：
A computer implemented method of load shedding used in stream computing system that considers the relative importance of each of the applications processing the incoming input data or events. The method of load shedding method also accounts for system physical constraints, such as memories and CPU utilization. The load shedding method first observes the workload of each application and arriving rate of the incoming input data or events. If the system is under an overloading condition, calculate a input data or event drop ratio for each application such that the projected sum of all applications' workload will be at or below the system capacity when the unprocessed input data or events are dropped according to the drop ratio for each application.
