Viper: An Efficient Hybrid PMem-DRAM Key-Value Store

Summary: Viper introduces three PMem-specific access patterns and a hybrid architecture combining a DRAM hash index with PMem-aware layout. It exploits DRAM random writes and PMem sequential writes, delivering 4–18× higher write throughput than prior KVSs while preserving persistence. (summarized by gpt-5.6-luna on Jul 24 2026)
