Stratosphere is a DFG-funded research project and investigates "Information Management on the Cloud".

The Stratosphere System is an outcome of our research project and openly available under Apache License, Version 2.0.
At the current state, the system consists of:

  • the PACT Programming Model
  • the Nephele Execution Engine

The system is highlighted by the following features:

  • Easy definition and massively parallel execution of complex data analysis tasks.
  • PACT is a generalization and extension of the well-known MapReduce programming model.
  • A cost-based optimizer compiles PACT programs to Nephele dataflow graphs.
  • Nephele executes dataflow graphs in a massively parallel and very flexible fashion.

You can download the Stratosphere System from our Download page.
