摘要

现代操作系统上的应用程序在内存中管理它们的临时状态，在磁盘上管理它们的持久状态。确保它们之间的一致性是开发人员大量工作和应用程序错误的来源。我们介绍了Aurora单级存储，这是一个消除了短暂和持久应用程序状态之间区别的操作系统。Aurora以毫秒级的粒度持续持久化整个应用程序，以提供作为操作系统服务的持久化。Aurora通过单层存储的视角重新审视了应用程序检查点的问题。Aurora支持透明和定制的应用程序。使用Aurora api的RocksDB数据库在删除40%代码的同时，吞吐量提高了75%。

The Aurora Single Level Store Operating System

Applications on modern operating systems manage their ephemeral state in memory and persistent state on disk. Ensuring consistency between them is a source of significant developer effort and application bugs. We present the Aurora single level store, an OS that eliminates the distinction between ephemeral and persistent application state. Aurora continuously persists entire applications with millisecond granularity to provide persistence as an OS service. Aurora revists the problem of application checkpointing through the lens of a single level store. Aurora supports transparent and customized applications. The RocksDB database using Aurora's APIs achieved a 75% throughput improvement while removing 40% of its code.
