1.1.8 How Big Can MySQL Tables Be?
MySQL Version 3.22 has a 4G limit on table size. With the new MyISAM in MySQL Version 3.23 the maximum table size is pushed up to 8 million terabytes (2 ^ 63 bytes).
Note, however, that operating systems have their own file size limits. Here are some examples:
Operating System
File Size Limit
Linux-Intel 32 bit
2G, 4G or more, depends on Linux version
Linux-Alpha
8T (?)
Solaris 2.5.1
2G (possible 4G with patch)
Solaris 2.6
4G
Solaris 2.7 Intel
4G
Solaris 2.7 ULTRA-SPARC
8T (?)
On Linux 2.2 you can get bigger tables than 2G by using the LFS patch for the ext2 file system. On Linux 2.4 there exists also patches for ReiserFS to get support for big files.
This means that the table size for MySQL is normally limited by the operating system.
