A Workload Generator for Database System Benchmarks

There are cases in which database system benchmarks should be executed in a realistic environment to get meaningful performance results. We propose a workload generator that helps benchmarks be executed in an environment similar to the real world in terms of resource status. The workload generator can create memory-bound, CPU-bound, and I/O-bound workloads. The workload generator allows users to create a composite workload, which is similar to real workload users run across in practice. Finally, using TPC-C and the Wisconsin benchmark, we conduct an experiment to show the feasibility of the proposed workload generator.
