摘要

本文提出了一个在Java中高效访问非易失性主存储器(NVMM)的框架J-NVM。J-NVM提供了一个完全成熟的接口，使用故障原子块来持久化普通Java对象。这个接口在内部依赖于代理对象，代理对象中间直接对NVMM进行堆外访问。该框架还提供了一个高度优化的持久数据类型库，可以抵抗重启和断电。我们通过为Infinispan数据存储实现持久后端来评估J-NVM。我们使用类似TPC-B的基准测试和YCSB获得的实验结果表明，J-NVM在Java中访问NVMM时始终比其他方法更快。

J-NVM: Off-heap Persistent Objects in Java

This paper presents J-NVM, a framework to access efficiently Non-Volatile Main Memory (NVMM) in Java. J-NVM offers a fully-fledged interface to persist plain Java objects using failure-atomic blocks. This interface relies internally on proxy objects that intermediate direct off-heap access to NVMM. The framework also provides a library of highly-optimized persistent data types that resist reboots and power failures. We evaluate J-NVM by implementing a persistent backend for the Infinispan data store. Our experimental results, obtained with a TPC-B like benchmark and YCSB, show that J-NVM is consistently faster than other approaches at accessing NVMM in Java.
