本文以MySQL数据库为研究对象,讨论与数据库索引相关的一些话题。特别需要说明的是,MySQL支持诸多存储引擎,而各种存储引擎对索引的支持也各不相同,因此MySQL数据库支持多种索引类型,如BTree索引,哈希索引,全文索引等等。

There may be many reasons that brought you here, it could be because you heard all about Hadoop and what it can do to crunch petabytes of data in a reasonable amount of time. While reading into Hadoop you found that for random access to the accumulated data there is something call HBase. Or it was the hype that is prevalent these days addressing a new kind of data storage architecture. It strives to solve large scale data problems where traditional solutions may either be too involved or cost prohibitive. A common term used in this area is NoSQL.
