Nephele/PACTs: A Programming Model and Execution Framework for Web-Scale Analytical Processing

by Dominic Battré, Stephan Ewen, Fabian Hueske, Odej Kao, Volker Markl, Daniel Warneke - In SOCC’10
"... We present a parallel data processor centered around a programming model of so called Parallelization Contracts (PACTs) and the scalable parallel execution engine Nephele [18]. The PACT programming model is a generalization of the well-known map/reduce programming model, extending it with further se ..."

MapReduce and PACT- Comparing Data Parallel Programming Models

by Er Alex, Stephan Ewen, Max Heimel, Fabian Hueske, Odej Kao, Volker Markl, Erik Nijkamp, Daniel Warneke
"... Abstract: Web-Scale Analytical Processing is a much investigated topic in current research. Next to parallel databases, new flavors of parallel data processors have re-cently emerged. One of the most discussed approaches is MapReduce. MapReduce is highlighted by its programming model: All programs e ..."

Reduce, such as operations with multiple inputs. The Nephele/PACT system uses a programming model that pushes the idea of MapReduce further. It is centered around so called Parallelization Contracts (PACTs), which are in many cases better suited to express complex operations than plain MapReduce. By the virtue
