MySQL 8.0 Reference Manual  /  ...  /  The INFORMATION_SCHEMA INNODB_TABLESPACES_BRIEF Table

Pre-General Availability Draft: 2018-01-12

25.32.25 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, 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.

Table 25.27 INNODB_TABLESPACES_BRIEF Columns

Column nameDescription
SPACETablespace Space ID.
NAMEThe database and table name.
PATHThe 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.
FLAGBit-level data about tablespace format and storage characteristics.
SPACE_TYPEThe 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;
+-------+---------+---------------+-------+------------+
| SPACE | NAME    | PATH          | FLAG  | SPACE_TYPE |
+-------+---------+---------------+-------+------------+
| 7     | test/t1 | ./test/t1.ibd | 16417 | Single     |
+-------+---------+---------------+-------+------------+
