Evaluation of Load Prediction Techniques for Distributed Stream Processing
This work tackles resource management challenges in DSP systems for data-intensive applications, but it is incremental as it focuses on evaluating existing methods rather than introducing new ones.
The paper evaluated load prediction techniques for distributed stream processing (DSP) systems to address workload variability, finding that deep learning methods provided the most accurate predictions across nine datasets from IoT, Web 2.0, and cluster monitoring domains.
Distributed Stream Processing (DSP) systems enable processing large streams of continuous data to produce results in near to real time. They are an essential part of many data-intensive applications and analytics platforms. The rate at which events arrive at DSP systems can vary considerably over time, which may be due to trends, cyclic, and seasonal patterns within the data streams. A priori knowledge of incoming workloads enables proactive approaches to resource management and optimization tasks such as dynamic scaling, live migration of resources, and the tuning of configuration parameters during run-times, thus leading to a potentially better Quality of Service. In this paper we conduct a comprehensive evaluation of different load prediction techniques for DSP jobs. We identify three use-cases and formulate requirements for making load predictions specific to DSP jobs. Automatically optimized classical and Deep Learning methods are being evaluated on nine different datasets from typical DSP domains, i.e. the IoT, Web 2.0, and cluster monitoring. We compare model performance with respect to overall accuracy and training duration. Our results show that the Deep Learning methods provide the most accurate load predictions for the majority of the evaluated datasets.
