Distributed data stream processing systems (DSPSs) such as Storm, Flink, and Spark Streaming are now routinely used to process continuous data streams in (near) real-time. However, achieving the low latency and high throughput demanded by today's streaming applications can be a daunting task, especially since the performance of DSPSs highly depends on a large number of system parameters that control load balancing, degree of parallelism, buffer sizes, and various other aspects of system execution. This tutorial offers a comprehensive review of the state-of-the-art automatic performance tuning approaches that have been proposed in recent years. The approaches are organized into five main categories based on their methodologies and features: cost modeling, simulation-based, experiment-driven, machine learning, and adaptive tuning. The categories of approaches will be analyzed in depth and compared to each other, exposing their various strengths and weaknesses. Finally, we will identify several open research problems and challenges related to automatic performance tuning for DSPSs.
The performance implications of tuning are well-known in the industry, with good configurations leading to significant performance benefits, while bad ones can cause severe performance degradation. A substantial amount of research has been introduced in the last few years for automating performance tuning in DSPSs using a variety of approaches, classified into five categories: cost modeling, simulation-based, experiment-driven, machine learning, and adaptive tuning. The above table outlines and compares the various key features and functionalities of approaches falling in the five categories in terms of modeling, need for statistics or runs, prediction accuracy, and adaptability to workload and system changes. These approach categories will be examined in depth and compared within the context of DSPSs during this tutorial.
The tutorial is planned for 1.5 hours (90 minutes) and will have the following structure:
