Analysis and Evaluation of Using Microsecond-Latency Memory for In-Memory Indices and Caches in SSD-Based Key-Value Stores

Summary: Analyzes offloading in-memory indices/caches of SSD-backed KV stores to microsecond-latency secondary memory and evaluates impact on pointer-chasing throughput; shows software prefetching from user threads remains effective. Presents a model coupling prefetching and IO, derives an equation quantifying throughput degradation, and shows IO overlap largely masks a few-microsecond memory penalty.
