In the process of using MySQL, there are some questions about the concepts of MyISAM and InnoDB, and the difference between the two engines has always been a question in my mind. In order to solve this puzzle, search the network, found the following

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

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

Based on practical experience, this paper introduces an open source MySQL database innodb data recovery tool: Innodb-tools, which recovers data from lost or corrupted MySQL tables by extracting Row records from the original data file. For example,

InnoDB Storage Engine1. Storage: Data directory. Can be modified by configurationStore file: Frm,ibd end of file. FRM storage table structure, IBD stores indexes and dataStorage log: Ib_logfilen file2.INNODB storage engine turned on or off:Close

InnoDB maintains a cache of data and index information to the memory of the storage area called buffer pool, which caches the most recently accessed data. By configuring the parameters of each buffer pool, we can significantly improve the

MyISAM: This is the default type, which is based on the traditional ISAM type, ISAM is an abbreviation for indexed sequential access method (indexed sequential access methods), which is the standard way to store records and files. Compared to other

MySQL, as the most popular free database service engine, has been popular for a long time. However, some people may not know much about the internal environment of MySQL, especially those mechanisms for concurrent processing. Today, let's take a

Because books are borrowed from the library, write down some learning processes for future viewing. 1. The lock mechanism is used to manage concurrent access to shared files. InnoDB uses row-level locks. MyISAM uses table-level locks. In the case of

MyISAM is the default database engine for MySQL (prior to version 5.5), which was improved by the early ISAM (Indexed sequential access method: Indexed sequential access methods). Although performance is excellent, there is one drawback: Transaction
