Reflections on Almost Two Decades of Research into Stream Processing: Tutorial

Abstract

Ever since the need for new approaches and systems to handle data streams was identified in early 2000s, stream processing has been an active area of research, resulting in a large body of work with significant impact. This tutorial reflects on this research history by highlighting a number of trends and best practices that can be identified in hindsight. It also enumerates a list of directions for future research in stream processing.
