  Abstract: The management and usage of state are issues of paramount importance in big data processing systems (BDPS) today. They are increasingly gaining attention due to their utility in supporting complex operations in various applications. In this paper, we survey state management in BDPS and introduce a taxonomy to classify current research in this field by key characteristics. First, we present some of the most important applications of state. Then, we discuss the handling and implementation of state. Finally, we show some potential research directions in state management. This article aims to provide insight into the varying state management techniques in the literature, motivate others to pursue research in this field, and present some open questions.
