高性能MySQL第二版中的一個過期表述

在高性能MySQL第二版中文版的1.5.1小節中,在MySQL架構第一章中介紹：

做爲MySQL的默認存儲引擎，在性能和可用特徵之間，MyISAM提供一種良好的平衡，

這些特徵包括全文檢索，壓縮，空間函數。MyISAM不支持事務和行級鎖。

這是由於寫書是MySQL的版本尚未到5.1

https://dev.mysql.com/doc/refman/5.5/en/innodb-introduction.html

InnoDB is a general-purpose storage engine that balances high reliability and high performance. Starting from MySQL 5.5.5, the default storage engine for new tables is InnoDB rather than MyISAM. Unless you have configured a different default storage engine, issuing a CREATE TABLE statement without an ENGINE= clause creates an InnoDB table. Given this change of default behavior, MySQL 5.5 might be a logical point to evaluate whether tables that use MyISAM could benefit from switching to InnoDB.

在5.5.5以後，InnoDB已經成爲了MySQL的默認存儲引擎

InnoDB includes all the features that were part of the InnoDB Plugin for MySQL 5.1, plus new features specific to MySQL 5.5 and higher.
