MYSQL Tutorial: maximum data table size limit
Restrictions on data table sizes for different MySQL Data Table types:
The maximum size of a single. ISD and. ISM file in the ISAM data table is 4 GB;
The default maximum size of a single. MYD and. MYI file in the MyISAM data table is also 4 GB. However, you can use the AVG_ROW_LENGTH and MAX_ROWS options to increase the maximum value to 8 million TB when creating the data table.
The maximum size of a MERGE data table is the sum of the maximum sizes of its various MyISAM data tables.
The size of the BDB data table is limited by the maximum size of the. db file allowed by the BDB processing program. The maximum size varies with the page size of the data table (determined at compilation), but the maximum size of the. db file can be 2 TB even if the smallest page size is 512 bytes.
The maximum tablespace size of the InnoDB data table is 4 billion pages. The default page size is 16 K. The value can be between 8 K and 64 K, which is determined during compilation. The maximum size of the InnoDB data table is the maximum size of the tablespace.
The size of a file is limited by the operating system. Generally, the size of a single file cannot exceed 2 GB. This constraint limits database files. InnoDB data tables can bypass this restriction by using unformatted hard disks as tablespaces.
For data tables that store two files separately from the data and index, if any file reaches the maximum size of the operating system file, the maximum size of the database table is reached.
Tables that contain the AUTO_INCREMENT data column are limited by the maximum upper limit of the data column type.
Because InnoDB data tables are managed using tablespaces, a single tablespace can contain multiple data tables in the same time and space, the maximum size of the data table is limited by the space of the system file and the data table in the same tablespace.
