myisam vs innodb performance

Differences between engineinnodb and enginemyisam in mysql introduction bitsCN.com when MySQL Administrator is used to create a database, the table is of the InnoDB type by default, so it does not matter. Later, when using Access2MySQL to export data, I found that only tables of the MyISAM type can be imported. I checked the differences between the two types. Originally, the

below 16-32MB to accommodate the temporary table indexes that are given to the disk. Innodb_buffer_pool_size-This is very important for the InnoDB table. InnoDB is more sensitive to buffering than MyISAM tables. MyISAM can be run under the default Key_buffer_size settings, however

MyISAM: This is the default type. It is based on the traditional isam type, and isam is the abbreviation of indexed sequential access method (sequential access method with indexes, it is a standard method for storing records and files. compared with other storage engines, MyISAM has most tools for checking and repairing tables. myISAM tables can be compressed and

MyISAM InnoDB the difference in composition: Each myisam is stored as three files on disk. The first file name begins with the name of the table, and the extension indicates the file type.The. frm file stores the table definition.The data file has an extension of. MYD (MYData).The extension of the index file is. MYI (Myindex

Always thought that I did not configure the spring things, the results found that the MySQL table itself is set to the MyISAM engine.

It is very suitable for distributed environments or data mart environments. · Cluster/NDB: MySQL's Cluster-based database engine is especially suitable for applications with high-performance search requirements. Such search requirements also require the highest normal working time a

When I first used MySQL Administrator to create a database, the table is of the InnoDB type by default, so I did not care about it. Later, when using Access2MySQL to export data, I found that only tables of the MyISAM type can be imported. I checked the differences between the two types. Originally, the MyISAM type does not support advanced processing such as tra

first column of the combined index.6. Table Lock DifferenceMyISAM: Only table-level locks are supported, and when the user operates the MyISAM table, the Select,update,delete,insert statement automatically locks the table, and if the locking table satisfies insert concurrency, new data can be inserted at the end of the table.InnoDB: Supports transactional and row-level locks, which are the InnoDB of the mo
