Mysql 数据库的表(table)大小一般由操作系统单个文件大小限制决定,并不是由mysql 内核决定;
常见os机器文件大小限制:
Operating System |
File-size Limit |
Win32 w/ FAT/FAT32 |
2GB/4GB |
Win32 w/ NTFS |
2TB (possibly larger) |
Linux 2.2-Intel 32-bit |
2GB (LFS: 4GB) |
Linux 2.4+ |
(using ext3 file system) 4TB |
Solaris 9/10 |
16TB |
OS X w/ HFS+ |
2TB |
Innodb 存储引擎通过tablespace 来维护innodbtables;而表空间可以有多个数据文件,这些表空间可以使用raw disk partitions。而表空间最大可以达到64TB;那么换句话说在使用innodb引擎时,他的数据库表可以达到64T;
如何扩张innodbtablespace 空间:
Mysql manual reference:Section14.4.2, “Changing the Number or Size of InnoDB Log Files”
4096 columns per table
a maximum row size of 65,535 bytes
InnoDB permits up to 1000 columns.
?InnoDB restricts row size to something less than half a databasepage (approximately 8000
bytes), not including VARBINARY, VARCHAR,BLOB, or TEXT columns
InnoDB
permits up to 4 billion tables. From mysql 5,.5
