A Scalable XML P2P Query System
نویسندگان
چکیده
This paper presents the architecture and the self-management algorithms of XPeer, a p2p XML database system. Unlike existing p2p systems, XPeer is capable of self-organizing its administrative layers, so to adapt to changes in the network topology and in the workload. The architecture of XPeer is based on two innovative concepts: the presence of two distinct subsystems (which we call overlays), devoted, respectively, to the management of queries and of schema update requests; and the use of cloning in order to distribute load among the administrative peers. By exploiting these key features, the actual workload processing power of XPeer can scale linearly in the number of peers in the system.

متن کاملTowards Internet-Scale Cardinality Estimation of XPath Queries over Distributed XML Data
In the last decade, we have witnessed a huge success of the peerto-peer (P2P) computing model. This has lead to the development of many Internet-scale applications and systems that are used commercially. Recently, the problem of computing statistics over data in Internet-scale systems has received attention. In this paper, we discuss the problem of cardinality estimation of XPath queries over d...
متن کاملTowards P2P XML Database Technology
To ease the development of data-intensive P2P applications, we envision a P2P XML Database Management System (P2P XDBMS) that acts as a database middle-ware, providing a uniform database abstraction on top of a dynamic set of distributed data sources. In this PhD work, we research which features such a database abstraction should offer and how it can be realised efficiently by extending and com...
متن کاملScalable DHT- and ontology-based information service for large-scale grids
Current grid information services are centralized or hierarchical and prove inefficient as the scale of the grid rapidly increases. The introduction of the P2P DHT technique into grids brings an encouraging path. However, current applications of the P2P DHT technique to grids do not consider the Virtual Organization (VO) management mode of grid resources. Frequent joining and leaving of resourc...
متن کاملDistributed Query Processing and Catalogs for Peer-to-Peer Systems
Peer-to-peer (P2P) architectures are commonly used for file-sharing applications. The reasons for P2P’s popularity in file sharing – fault tolerance, scalability, and ease of deployment – also make it a good model for distributed data management. In this paper, we introduce a scalable P2P framework for distributed data management applications using mutant query plans: XML serializations of alge...
