摘　　要：1 Introduction and main contributiions Emerging hardwares like remote Direct Memory Access(RDMA)capable networks and persistent memory(PM)are promising to build fast high availability in-memory key-value stores.The recent advent of Intel Optane DC Persistent Memory Modules(Optane DCPMM)brings the future closer.However,existing studies to combine the two devices cannot deliver the desired performance due to their two-phase protocols for log shipping and most of them were based on emulation that perform sub-optimally on real PM hardware.
