An analysis of performance factors on Esper-based stream big data processing in a virtualized environment

SUMMARY To process big data in a cloud computing environment, a large scale of stream big data is one of the challenging issues. In particular, complex event processing is an emerging technology to handle massive events from multiple sources and process them in a near real time. In this paper, we analyze four performance‐influencing factors on a virtualized event processing system: the number of query statements, garbage collection intervals,...
