FlatStore: Log-Structured KV Storage Engine for PM 该篇文章来自于 ASPLOS20 - FlatStore: An Efficient Log-Structured Key-Value Storage Engine for Persistent Memory 要解决的主要问题是现阶段的 PM 上的 KV 存储都没能充分利用 NVM 的带宽,出发点其实也是发现生产环境中的 KV 负载大多是小 KV 整个方案还...
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage devices, for data processing and storage. One of the systems includes a multi-tier storage subsystem including multiple tiers of storage devices, an input/out (I/O) subsystem that is ...
SSTable and Log Structured Storage: LevelDB If Protocol Buffers is thelingua franca of individual data record at Google, then the Sorted String Table (SSTable) is one of the most popular outputs for storing, processing, and exchanging datasets. As the name itself implies, anSSTable is a simple...
A log-structured storage is provided for use with journal data sets and a two-phase commit process. The log-structured storage provides a space release function for the journal data sets, wherein one or more portions of the journal data sets that are no longer required are marked as free ...

Free space collection in a log structured storage system. In response to receiving a request to collect free space, the segment in a recently invalidated segment list having the largest cumulative sum of invalidation duration values is selected for free space collection if this cumulative sum is la...
在当今信息时代,数据的存储和管理变得越来越重要。无论是云存储、数据库还是分布式文件系统,都需要高效的数据存储和检索方法。其中,LSM树(Log-Structured Merge Tree)是一种高性能的数据结构,广泛应用于各种分布式存储系统和数据库引擎中。本文将介绍LSM树的原理,并探讨其在不同使用场景中的应用。
A log-structured write cache for a data storage system and method for improving the performance of the storage system are described. The system might be a RAID storage array, a disk drive, an optical disk, or a tape storage system. The write cache is preferably implemented in the main stor...
