MyISAM table. MyISAM storage format is the default type in MySQL since version 3.23, and it has the following features:
If the operating system itself allows larger files, then the file is larger than the ISAM storage method.
The data is stored in a machine-independent format with low byte precedence. This means that tables can be copied from one machine to another, even if they are different architectures.
Numeric index values account for less storage space because they are stored in high-byte precedence. Index values change quickly in low-level bytes, so high-bit bytes are easier to compare.
Auto_increment processing is better than the ISAM table. The detailed content is discussed in the 2nd Chapter.
Several index limits are reduced. For example, columns with NULL values can be indexed, and columns of BLOB and TEXT types can also be indexed.
To improve the integrity checking of a table, each table has a flag that is set after MYISAMCHK checks the table. You can use Myisamchk-fast to skip checking for tables that have not been modified since the previous check, which makes this management task faster. The table also has a flag indicating whether the table is gracefully closed. If the server shuts down or the machine crashes, this flag can be used to detect the table that needs to be checked when the server is started.
