28.4.25 The INFORMATION_SCHEMA INNODB_TABLESPACES_BRIEF Table

TheINNODB_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 asFS_BLOCK_SIZE,FILE_SIZE, andALLOCATED_SIZE, must be loaded dynamically.

Space and path metadata is also provided by theINNODB_DATAFILES table.

TheINNODB_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 ofschema/table_name.

  • PATH

    The tablespace data file path. If afile-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 includeGeneral forInnoDB general tablespaces,Single forInnoDB file-per-table tablespaces, andSystem for theInnoDB 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     |+-------+---------+---------------+-------+------------+
