QTor: A Flexible Publish/Subscribe Peer-to-Peer Organization Based on Query Rewriting

Tuesday, October 6, 2015 - 13:00 to 14:00
Nautibus, salle C5

Peer-to-peer publish/subscribe architectures are an interesting support for scalable distributed data stream applications. Most approaches, often based on brokers, have a static organization which is not much adaptive to different configurations of the participants’ capacities. We present QTor (Query Torrent) a generic organization that enables dynamic adaptation providing a continuum from centralized to fully decentralized solutions. Based on query rewriting and equivalence, QTor proposes a definition ofcommunities and their relations that decouples the logical and physical aspects of the problem, while efficiently reducing organizational and functional costs.
