DocDesign 2.0: Automated database design for document stores with multi-criteria optimization

Abstract

We present DocDesign 2.0, a novel system that supports database design for document stores. DocDesign 2.0 automatically generates a document store design driven by a query workload and a set of optimization objectives. In the presence of a massive search space, DocDesign 2.0 adopts multi-objective optimization techniques that, with high probability, guarantee to yield the optimal design based on the preferences (i.e., weights) provided by the end-user. In this paper, we demonstrate how DocDesign 2.0 improves the productivity on the task of designing a document store, as well as how the quality of the results is improved with respect to those obtained by manually generating the design.
