In the area of Big Data Processing, the focus of the DS group is on the design, implementation, analysis, and benchmarking big-data processing systems. Specific research topics are:

• Designing and analyzing big-data processing systems

We have designed and analyzed of the BTWorld MapReduce-based workflow for analyzing monitoring data of the world-wide BitTorrent P2P system. With this work, we won the SCALE challenge at the CCGrid 2014 conference:

• Large-scale graph processing

We are in the process of designing and implementing the Graphalytics graph processing benchmarking in collaboration with Intel Labs and Oracle.

• Large-scale privacy-preserving video distribution

Here is a video explaining our research.
