摘要: Real-time stream processing has become increasingly important in recent years and led to the development of a multitude systems. Given varying job workloads that characterize processing, these systems need be tuned adjusted maintain performance targets face variation incoming traffic. Current auto-scaling adopt series trials approach job's expected due lack modelling tools. We find general traffic trends most jobs lend themselves well prediction. Based on this premise, we built system called Caladrius forecasts future load predicts its after proposed change parallelism operators. Experimental results show is able estimate throughput CPU under given scaling configuration.
