Abstract
One embodiment of the present method and apparatus adaptive in-operator load shedding includes receiving at least two data streams (each comprising a plurality of tuples, or data items) into respective sliding windows of memory. A throttling fraction is then calculated based on input rates associated with the data streams and on currently available processing resources. Tuples are then selected for processing from the data streams in accordance with the throttling fraction, where the selected tuples represent a subset of all tuples contained within the sliding window.
