作为MySQL的默认存储引擎,在性能和可用特征之间,MyISAM提供一种良好的平衡,
这些特征包括全文检索,压缩,空间函数。MyISAM不支持事务和行级锁。
这是因为写书是MySQL的版本还没有到5.1

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之后,InnoDB已经成为了MySQL的默认存储引擎
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.
