Database systems have traditionally used a Client-Server architecture. As the server becomes overloaded, clients experience an increase in query response time, and in the worst case the server may be unable to provide any service at all. In file-sharing, the problem of server overloading has been addressed by the use of Peer-to-Peer (P2P) techniques in which users (peers) supply files to each other, so sharing the load. This paper describes the Wigan P2P Database System, which was designed to investigate if P2P techniques for reducing server load, thus increasing system scalability, could be applied successfully in a database environment. It is based on the BitTorrent file-sharing approach. This paper introduces the Wigan system architecture, explaining how the BitTorrent approach must be modified for a P2P database server. It presents and analyses experimental results, including the TPC-H benchmark, which show that the approach can succeed in delivering scalability in particular cases.
