什么是“面向文档” vs. Key-Value在谈论MongoDB和Cassandra时的平均值？ [英] What does "Document-oriented" vs. Key-Value mean when talking about MongoDB vs Cassandra?

问题描述

解决方案

使用基于文档的NoSQL选项会如何处理您的KV商店？最大的区别是一个面向文档的数据库支持二级索引，K / V不支持。一般来说，面向文档的dbs往往允许更丰富的查询，允许类似范围查询，排序和其他类型的高级操作。

What does going with a document based NoSQL option buy you over a KV store, and vice-versa?

解决方案

The biggest difference is that a document-oriented database supports secondary indexes, K/V does not. In general, document-oriented dbs tend to allow richer queries, allowing things like range queries, sorting, and other types of "advanced" operations.
