CQ-Buddy: Harnessing Peers For Distributed Continuous Query Processing

In this paper, we present the design and evaluation of CQ-Buddy, a peer-to-peer (p2p) continuous query (CQ) processing system that is distributed, and highly-scalable. CQ-Buddy exploits the differences in capabilities (processing and memory) of peers and load-balances the tasks across powerful and weak peers. Our main contributions are as follows: First, CQ-Buddy introduces the notion of pervasive continuous queries to tackle the frequent disconnected problems common in a peer-to-peer environment. Second, CQ-Buddy allows for inter-sharing and intra-sharing in the processing of continuous queries amongst peers. Third, CQ-Buddy peers perform query-centric load balancing for overloaded data source providers by acting as proxies. We have conducted extensive studies to evaluate CQ-Buddy’s performance. Our results show that CQ-Buddy is highly scalable, and is able to process continuous queries in an effective and efficient manner. / Singapore-MIT Alliance (SMA)
