Standard benchmarks are essential tools to enable developers to validate and evaluate their systems design in terms of both relevant properties and performance. Benchmarks provide the means to evaluate a system with workloads that mimics real use cases. Although a large number of benchmarks exist for database system, there is a lack of standard benchmarks for an increasingly relevant class of storage systems - geo-replicated key-value stores providing weak consistency guarantees. This has led developers and researchers to rely on ad-hoc tools, whose results are both hard to reproduce and compare. In this paper, we propose the first standardized benchmark specially tailored for weakly consistent key-value stores. The benchmark, named FMKe, is modeled after a real application - the Danish National Joint Medicine Card. The benchmark is scalable, it can be parameterized to emulate a large number of access patterns, and it is also highly flexible, enabling its application on systems that offer different consistency guarantees and mechanisms.
