## 26.4.27 The INFORMATION_SCHEMA INNODB_TABLESPACES_BRIEF Table 

The INNODB_TABLESPACES_BRIEF  table provides space ID, name, path, flag, and space type metadata for file-per-table, general, undo, and system tablespaces. 

INNODB_TABLESPACES  provides the same metadata but loads more slowly because other metadata provided by the table, such as FS_BLOCK_SIZE , FILE_SIZE , and ALLOCATED_SIZE , must be loaded dynamically. 

Space and path metadata is also provided by the INNODB_DATAFILES  table. 

The INNODB_TABLESPACES_BRIEF  table has these columns: 

• SPACE 

The tablespace ID. 

• NAME 

The tablespace name. For file-per-table tablespaces, the name is in the form of schema/table_name . 

• PATH 

The tablespace data file path. If a file-per-table tablespace is created in a location outside the MySQL data directory, the path value is a fully qualified directory path. Otherwise, the path is relative to the data directory. 

• FLAG 

A numeric value that represents bit-level information about tablespace format and storage characteristics. 

• SPACE_TYPE 

The type of tablespace. Possible values include General  for InnoDB  general tablespaces, Single  for InnoDB  file-per-table tablespaces, and System  for the InnoDB  system tablespace. 

## Example 

mysql> SELECT * FROM INFORMATION_SCHEMA.INNODB_TABLESPACES_BRIEF WHERE SPACE = 7;
