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...
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage devices, for data processing and storage. One of the methods includes maintaining, by a storage system, a data log file in a source storage device of the storage system. The storage ...
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...
本文主要介绍了Zoned Storage(分区存储)技术在云计算和大数据应用中的重要性和实用性。Zoned Storage是一种新兴的存储技术,通过将数据划分为不同的区域,以优化SSD和HDD的性能和寿命。文章提到了多个Zoned Storage的实现,如ZenFS、Longhorn、Ceph、OpenEBS-Mayastor和SPDK CSAL,以及它们在Kubernetes和容器存储中的应用。
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 ...
这个KV Store采用的是NVM Log Structure + 内存索引的结构,数据先写入NVM Op log,再更新内存索引。其中NVM log structure针对Optane DC的特性设计了Compacted Oplog以及Lazy-Persisted Allocator,并提出Pipelined Horizontal Batch技术优化了batch写入的过程。 背景...

The Bw-Tree is a high performance latch-free B-tree index that exploits log-structured storage. Its design addresses two emerging hardware platform trends. (1) Multi-core and main memory hierarchy: the Bw-tree is completely latch-free; it performs state changes (e.g., record updates,...
