PIER on PlanetLab: Initial Experience and Open Problems
Ryan Huebsch, Brent N. Chun, Joseph M. Hellerstein, Brent N. Chun · 2003
In this paper we describe our initial experiences with deploying and running PIER, a distributed query processor, on 200 nodes of the PlanetLab network testbed. Through use cases, we show that PIER is flexible and can easily incorporate new data sources without a priori knowledge of their schemas. We highlight of number of important features in PIER used in our use cases, including in-network aggregation. Finally, we discuss open problems that are raised by our work to date.
