Recently, several policies have been proposed for scheduling multiple Continuous Queries (CQs) in a Data Stream Management System (DSMS). The decision on which policy to use plays an important role in shaping the percieved online performance provided by the DSMS. In this tutorial, we provide an overview of different policies employed by current CQ schedulers and the performance goals optimized by these policies. Further, we discuss the salient properties of CQs conisdered by current policies as well as the efficent implementation of such policies into CQ schedulers. Finally, we present future research directions and open problems in CQ scheduling.
