Persistent Memory Hash Indexes: An Experimental Evaluation
Summary: Direct comparison of six persistent-hash-table designs (Level hashing, CCEH, Dash, PCLHT, Clevel, SOFT) on real persistent memory using a unified benchmark. Analyzes hardware sensitivity (PM bandwidth, NUMA, CPU instructions) and outlines design trade-offs plus optimization directions for PM-based hash indexes. (summarized by gpt-5-nano on Feb 09 2026)
