Abstract

See full text

A method for processing a stream of tuples may comprise receiving a stream of tuples to be processed by a plurality of processing elements operating on one or more computer processors. In addition, the method may include generating a model of performance for processing the stream of tuples at runtime, wherein one or more tuples from the stream of tuples potentially cause adverse performance. Further, the method may comprise predicting a parameter for a tuple from the stream of tuples, the parameter indicating a potential for adverse performance, the predicting including using the model. The method may also include modifying processing of the tuple if the parameter falls outside a threshold.
