MySQL engine introduction ISAM, MyISAM, HEAP, InnoDB The MySQL Database Engine depends on how MySQL is compiled during installation. To add a new engine, you must recompile MySQL. By default, MySQL supports three engines: ISAM, MYISAM, and HEAP. The other two types of INNODB and BERKLEY (BDB) are also frequently used. If the technology is superb, you can use MySQL ++ API to build an engine. The following de

Introduction to the Database engineThe MySQL database engine depends on how MySQL was compiled when it was installed. To add a new engine, you must recompile MySQL. By default, MySQL supports three engines: ISAM, MyISAM, and heap. Two other types of InnoDB and Berkley (BDB) are also often available. If you're skilled, you can use MYSQL+API to make an engine yourself. Several database engines are described below:ISAM: ISAM is a well-defined and time-te
