Plush: A Write-Optimized Persistent Log-Structured Hash-Table

Summary: Plush: a write-optimized, persistent hybrid log-structured hash-table for PMem. It reduces media write amplification by ~80% and uses PMem's low write latency to reach 2.44x insert throughput with modest DRAM, while lookup throughput matches PMem-tree indexes.
