HiKV: A Hybrid Index Key-Value Store for DRAM-NVM Memory Systems

Abstract: This work presents HiKV, a hybrid index key-value store for hybrid memory systems. HiKV constructs multiple hash indexes and a global B+-Tree index to support both single-key operations and range scan. HiKV carefully designs the updating, concurrency and consistency of hybrid index to utilize the characteristics of hybrid memory. Evaluation results show that HiKV outperforms state-of-art NVM KV stores in micro- and macro- benchmarks.
