Peer-to-Peer Approaches to Query Processing in Internet-scale Networks
Query processing in Internet-scale networks poses challenges such as fully decentralized processing, instability of nodes and network, and heterogeneity of nodes. Though peer-to-peer (P2P) technologies have been widely adopted in Internet-scale applications, they are far from meeting the requirements for complex query processing in efficiency.In this paper, the challenges for designing a query processing engine over P2P network are discussed first.Then, some general considerations about the P2P-based query processing system andthe underlying ideas are presented. Based on these considerations, two approaches,say, pull-based and push-based query processing, are presented. Meanwhile, two prototyping systems, P-Terse and Sonnet, are introduced as efforts for implementing P2P query processing system with the two approaches,respectively. The former is a peer-to-peer based text retrieval and search system, and the latter is a subscription overlay network. This paper is a brief summary of the research and development work, which have been done in our research group.
