Resource management using pattern-based prediction to address bursty data streams

In the recent years we have witnessed a proliferation of distributed stream processing systems that need to operate efficiently, even when data bursts occur. Examples include road traffic networks, processing of financial feeds, network monitoring and real-time sensor data analysis systems. An important challenge in managing these systems is effective resource management and meeting the QoS demands of the stream processing applications under different workload conditions, even under bursts. In this paper we present our approach that aims to predict the execution times of the distributed stream processing applications by taking into account the effects of the bursts and what is the typical workload of the stream processing system. Our approach builds application data rate patterns at run-time and predicts the effect of the burst on the performance of the applications, to identify whether there is a need to react on the onset of a burst. Our detailed experimental results over our Synergy middleware illustrate that our approach is practical, depicts good performance and has low resource overhead.
