读MySQL技术内幕:InnoDB存储引擎

我简单理解MySQL就是三个部分:文件、存储引擎、各种组件。当然,没那么简单啦,组件类型有很多种,看图就很明了啦,虽然英文不怎么样,google下还是明白的,连接池、管理服务和工具、接口、查询分析、优化器、缓存。

有一个重要概念,插件式存储引擎,啥意思呢?所有人都可以开发存储引擎,可以随时更换的意思吗?网上查了查,大概和我想的是一致的,灵活性和可扩展性,甚至同一个数据库中的不同表可以使用不同的存储引擎,可以根据不同需求来选择数据库的存储引擎,比较牛逼。

网上也让我找到了这张图片,引用下啦,很明显可以看出各个存储引擎之间的区别,没有好与不好,只能说适用的场景不同,比较新奇的是Archive这种,只能进行INSERT和SELECT操作,而且用zlib算法进行压缩,比例达到1:10,对于像日志这种不许要修改的信息来讲,是最适合不过的啦。
