It's an electronic testing and examination environment for German universities. It's very far from big data, but we have to support very small universities with very limited tech budget. We pre-generate and store the exams to ensure that we do not have any compatibility issues in the future (e.g. by changing minute elements of the randomisation). The biggest database currently is about 700GB and I assume that we'll reach an equilibrium at around 2 TB.
