Using predictive determinism within a streaming environment
InactiveUS20130031335A1Program control using stored programsGeneral purpose stored program computerEngineeringProcessing element
Techniques are described for transmitting predicted output data on a processing element in a stream computing application instead of processing currently received input data. The stream computing application monitors the output of a processing element and determines whether its output is predictable, for example, if the previously transmitted output values are within a predefined range or if one or more input values correlate with the same one or more output values. The application may then generate a predicted output value to transmit from the processing element instead of transmitting a processed output value based on current input values. The predicted output value may be, for example, an average of the previously transmitted output values or a previously transmitted output value that was transmitted in response to a previously received input value that is similar to a currently received input value. Moreover, the processing element or elements that transmit the predicted output data may be upstream from the processing element with the predictable output.
