Dynamic extensible query processing in super-peer based P2P systems

To enable dynamic, extensible, and distributed query processing in super-peer based P2P networks, where standard query operators and user-defined code can be executed nearby the data, we distribute query processing to (super-) peers. Therefore, super-peers provide functionality for the management of the indices, query optimization, and query processing. Additionally, we expect that peers provide query processing capabilities to be full members of the P2P network. To enable this, super-peers have to provide an optimizer for generating efficient query plans from the queries they receive. The distribution process is guided by the routing index which is dynamic and corresponds to the data allocation schema in traditional distributed DBMSs.
