By default, MySQL supports three engines: ISAM, MyISAM, and heap. The other two types are InnoDB and Berkley (BDB). ISAM ISAM is a well-defined and time-tested method of data table management, designed to take into account that the number of times a database is queried is much larger than the number of updates. As a result, ISAM performs read operations quickly and does not consume large amounts of memory and storage resources. The two major drawbac

The storage engine in the database is actually a set of tables that use the engine, and the table in the database sets what storage engine, so the table has different "effects" in terms of how the data is stored, how the data is updated, the performance of the data query, and whether it supports indexing. There are multiple engines in the MySQL database (different versions of the MySQL database support the engine), familiar with the various

Because the storage of data in a relational database is stored as a table, the storage engine can also be called a table type (that is, the type that stores and operates this table).There is only one storage engine in a database such as Oracle and SQL Server, and all data storage management mechanisms are the same. The MySQL database provides a variety of st
