KVBench: A Key-Value Benchmarking Suite
Zichen Zhu, Arpita Saha, Manos Athanassoulis, Subhadeep Sarkar · 2024
Key-value stores are at the core of several modern NoSQL-based data systems, and thus, a comprehensive benchmark tool is of paramount importance in evaluating their performance under different workloads. Prior research reveals that real-world workloads have a diverse range of characteristics, such as the fraction of point queries that target non-existing keys, point and range deletes, as well as, different distributions for queries and updates, all of which have very different performance implications. State-of-the-art key-value workload generators, such as YCSB and db_bench, fail to generate workloads that emulate these practical workloads, limiting the dimensions on which we can benchmark the systems' performance.
