本文主要参考System Design Interview: An Insider’s Guide(CHAPTER 6) 键值存储(key-value store),也被称为键值数据库(key-value database),是一个非关系型数据库。每一个独特的标识符都被存储为一个带有相关值的键。这种数据配对被称为 "键-值 "对。 在一个键值对中,键必须是唯一的,与键相关的值可以通...

A key-value store that is using the file system for permanent storage and which offers a networking interface would cover the whole range of topics listed above. This is just the perfect project that deals with all domains of back-end engineering. 我开始这个项目是为了回顾后端开发的一些基础知识。
1.1 键值存储 (Key-value Store) Key-value键值对并非计算机科学的新颖概念。在数学和逻辑学中,我们称之为"有序对"或"元组"。例如,函数f(x) = x^2实际上就是键值对的集合;在逻辑学中,"如果-那么"的命题形式也是键值对。这些键值关系是许多计算机科学数据结构和数据库的基础,其中"键"用于唯一标识一个或者一...
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and...
Schema-less design.Unlike relational databases, key-value stores don't have a fixedschema. They allow for flexible data representation and diverse data structures within a single database. Flexibility makes it easy to evolve data structure over time or move key-value stores from one system to an...
Key-Value Store is a data storage system that stores data as a collection of key-value pairs, allowing for efficient retrieval and manipulation of data.
Other good resources for API design are Chapter 4 “Designs and Declarations” from “Effective C++” by Scott Meyers [3], and “Effective Java” by Joshua Bloch [4]. Those resources are very important at this stage of the key-value store project, though I ...
In the view of existing key/value caching system mass data access speed slow unable to meet the application requirements,put forward an improved key/value data storage scheme and applied it to the cache system.Put forward a small amout of data storage program and improved rehash algorithm the ...
