为什么MongoDB这么快 [英] Why Is MongoDB So Fast

问题描述

我向我展示了MongoDB与SQL 2008的同事性能基准，尽管他认为MongoDB更快，但他不知道这样做的可能性.他的逻辑是，SQL已经存在了几十年，并且有一些最聪明的人在使用它，MongoDB怎么能做到呢?一个相对较新的孩子在性能上如此出色?我无法真正提供可靠的技术答案，我希望你们能提供帮助.

I was showing my co-worker performance benchmarks of MongoDB vs SQL 2008 and while he believes MongoDB is faster, he doesn't understand how its possible. His logic, was that SQL has been around for decades, and has some of the smartest people working on it, and how can MongoDB; a relatively new kid on the block be so superior in performance? I wasn't able to really provide a solid and technical answer, and I was hoping you guys could assist.

推荐答案

MongoDB与传统的关系数据库不同.它是 noSQL 或基于文档的，它提供了较弱的一致性保证，并且不必保证一致性像SQL.

MongoDB isn't like a traditional relational database. It's noSQL or document based, it provides weak consistency guarantees, and it doesn't have to guarantee consistency like SQL.
