PastryStrings: A Comprehensive Content-Based Publish/Subscribe DHT Network

In this work we propose and develop a comprehensive infrastructure, coined PastryStrings, for supporting rich queries on both numerical (with range, and comparison predicates) and string attributes, (accommodating equality, prefix, suffix, and containment predicates) over DHT networks utilising prefix-based routing. As event-based, publish/ subscribe information systems are a champion application class, we formulate our solution in terms of this environment.
