Abstract
The byte-addressable persistent memory (PMEM) devices have opened new opportunities for building high-performance storage systems. With both DRAM and PMEM in the system, it is important to choose the correct storage data structures on each of them to achieve the best overall performance and the needed data persistence. However, this is non-trivial. One reason is the limited understanding of the actual performance characteristic of different data structures on PMEM. In this study, we develop storeds-bench to help developers better understand the overhead they will encounter when using a certain data structure on PMEM. Specifically, storeds-bench is designed as a benchmark suite that leverages YCSB and has various commonly used storage data structures implemented using PMDK (persistent memory develop kit) under different persistent and consistency requirements.
