Research Topic:

Large scale data analysis is an important activity in many organizations and it is typically carried out using data-intensive workflows. Such workflows generate large intermediate results which are reusable. Materialization of these results guarantees good performance. Current solutions use a single fixed storage layout to store the intermediate results. However, the same fixed layout is not optimal in all situations. Thus, a wise selection of the layout according to the workload can give the best overall performance. In this thesis, we are working on the selection of storage layouts for storing the intermediate results by considering the workload.
