Sketch-Based Geometric Monitoring of Distributed Stream Queries

Emerging large-scale monitoring applications rely on continuous tracking of complex data-analysis queries over collections of massive, physically-distributed data streams. Thus, in addition to the space- and time-efficiency requirements of conventional stream processing (at each remote monitor site), effective solutions also need to guarantee communication efficiency (over the underlying communication network). The complexity of the monitored query adds to the difficulty of the problem - this is especially true for nonlinear queries (e.g., joins), where no obvious solutions exist for distributing the monitor condition across sites.
