CacheKV

1 Introduction

This is the implementation of CacheKV described in the paper "Redesigning High-Performance LSM-based Key-Value Stores with Persistent CPU Caches". CacheKV is a LSM-Tree based KV store utilizing Persistent CPU Cache provided by Intel Optane Persistent Memory 200 Series. We implement CacheKV based on [NoveLSM] (https://github.com/sudarsunkannan/lsm_nvm).
