Redis和MongoDB之间的区别

1. Redis：
Redis代表Remote Dictionary Server，它是一个内存中数据结构项目，实现了具有可选持久性的分布式内存中键值数据库。 Redis由Redis实验室开发，最初于2009年5月10日发布。它是用ANSI和C语言编写的。 Redis提供了内存效率，快速的操作速度，高可用性，并提供了一些功能，例如可调性，复制，集群等。

2. MongoDB：
MongoDB是一个跨平台的面向文档的非关系(即NoSQL)数据库程序。它是一个开放源代码文档数据库，以键值对的形式存储数据。 MongoDB由MongoDB Inc.开发，最初于2009年2月11日发布。它使用C++，Go，JavaScript， Python语言编写。 MongoDB提供高速，高可用性和高可伸缩性。 Redis和MongoDB之间的区别：
