"Querying a DHT-based Universal Storage"

In recent time, the idea of collecting and combining large public data sets and services became more and more popular. The special characteristics of such systems and the requirements of the participants demand for strictly decentralized solutions. In this talk, we present our vision of a universal storage for structured data based on a P2P overlay and the universal relation model as its key enabling technologies to achieve flexibility, robustness, and efficiency for large-scale distributed data storage and query processing. We outline the challenges such a system has to overcome and discuss results we have already achieved in our work. Here, we focus on distributed processing of similarity-based queries as well as on the problem of query guarantees in terms of result completeness.
