Abstract
Quality-aware scheduling is a novel term employed in our study. However, the related work on this topic appeared in the 1990s. In this chapter, we briefly summarize the literature and research work on quality-aware scheduling. On the one hand, we overview the typical metrics for quality-aware scheduling, including QoS metrics and QoD metrics. On the other hand, we analyze the research progress on quality-aware scheduling in data management systems such as real-time database management system, data stream management system, relational database management system, and key-value data stores. In particular, the goal of quality-aware scheduling includes optimizing QoS, optimizing QoD, as well as optimizing both QoS and QoD. In the following, Sect. 2.1 illustrates metrics for quality-aware scheduling in term of QoS and QoD; Sect. 2.2 describes the research progress on quality-aware scheduling in data management system; Sect. 2.3 summarizes this chapter.
