Comparison between MySQL MyISAM engine and InnoDB Engine

The following articles mainly introduce the comparison of the actual performance of MySQL MyISAM engine and InnoDB engine, first, we use the table structure of the MySQL database to introduce the actual performance of the MySQL MyISAM engine and the InnoDB engine.

 
 

  
  
CREATE TABLE `myisam` (  
  
  
`id` int(11) NOT NULL auto_increment,  
  
  
`name` varchar(100) default NULL,  
  
  
`content` text,  
  
  
PRIMARY KEY (`id`)  
  
  
) ENGINE=MyISAM DEFAULT CHARSET=gbk;  
  
  
CREATE TABLE `innodb` (  
  
  
`id` int(11) NOT NULL auto_increment,  
  
  
`name` varchar(100) default NULL,  
  
  
`content` text,  
  
  
PRIMARY KEY (`id`)  
  
  
) ENGINE=InnoDB DEFAULT CHARSET=gbk;

$ Content = "MySQL supports several storage engines as processors for different table types. MySQL storage engine includes the engine for processing transaction security tables and the engine for processing non-transaction security tables: · MyISAM manages non-transaction tables. It provides high-speed storage and retrieval, as well as full-text search capabilities. MySQL MyISAM is supported in all MySQL configurations. It is the default storage engine, unless you configure MySQL to use another engine by default. ·

The MEMORY storage engine provides "in-MEMORY" tables. The MERGE storage engine allows a set to process the same MyISAM table as a separate table. Like MySQL MyISAM, MEMORY and MERGE storage engines process non-transaction tables. Both engines are included in MySQL by default.

Note: The MEMORY storage engine is officially identified as the HEAP engine. · InnoDB and BDB storage engines provide transaction security tables. BDB is included in the MySQL-Max binary distribution version released for the operating system that supports it. InnoDB is also included in all MySQL 5.1 binary distributions by default. You can configure MySQL to allow or disable any engine as you like. · The EXAMPLE storage engine is a "stub" engine, which does not do anything. You can use this engine to create tables, but no data is stored or retrieved from them. The purpose of this engine is to provide a service. In the MySQL source code example, it demonstrates how to start writing a new storage engine. Similarly, it is mainly interested in developers .";
