基于非易失存储器件的内存键值存储系统的性能研究
Study of the performance of in-memory key-value stores with non-volatile memory
摘要
Abstract
The application characteristics of in-memory key-value stores applicable to Internet applications to meet the high performance requirement of the back end storage system was analyzed .To avoid data losses in volatile DRAM memory, existing in-memory stores persist data into slow disk-based storage.Emerging non-volatile memories ( NVMs) , such as PCM and ReRAM , can sit on the memory bus due to their similar performance as DRAM .More-over , the inherent data durability in NVMs helps to accelerate data persisting when deploying in -memory key-value stores on NVMs.According to NVMs ' characteristics , in-memory key-value stores can exploit two architectures , u-sing NVM to replace Disk or using NVM to replace DRAM .Based on the above analysis, two types of NVM-based in-memory key-value stores were implemented , and then the experiments were conducted and some principles that effectively guide to choosing an appropriate architecture when in-memory key-value stores use different NVM de-vices.Also, the main software overhead in the two types of stores was concluded , and some future optimizing sug-gestions was given .关键词
