EvoBench – A Framework for Benchmarking Schema Evolution in NoSQL

Schema evolution is a timeless topic in database research. However, there is only a limited amount of research regarding benchmarking of NoSQL schema evolution systems available. To compare schema evolution systems regarding their overall capabilities and their efficiency to evolve schemas and migrate data, a standardized benchmark is required. In this article, we propose a conceptual framework for a NoSQL schema evolution benchmark with all required components. Beside the benchmark schema and its data sets, we provide the evolution workloads and the metrics as the benchmark's centerpiece in detail.
