- A file-per-table tablespace is a single-table tablespace that is created in its own data file rather than in the system tablespace. Tables are created in file-per-table tablespaces when the innodb_file_per_table option is enabled. Otherwise, InnoDB tables are created in the system tablespace. Each file-per-table tablespace is represented by a single .ibd data file, which is created in the database directory by default.
- file-per-table表空间是单表的表空间，它是在自己的数据文件中创建的，而不是在系统表空间中创建的,如果开启了innodb_file_per_table选项，则表创建在file-per-table表空间，否则，innodb表就会创建在系统表空间里面，每一个 file-per-table表空间是由一个.ibd 数据文件表示，默认是在数据库目录中创建的
- File per-table tablespaces support DYNAMIC and COMPRESSED row formats which support features such as off-page storage for variable length data and table compression. For information about these features, and about other advantages of file-per-table tablespaces, see Section 14.7.4, “InnoDB File-Per-Table Tablespaces”.
