The [Information Schema](/docs/server/reference/system-tables/information-schema.md) `INNODB_TABLESPACES_SCRUBBING` table contains [data scrubbing](/docs/server/server-usage/storage-engines/innodb/innodb-data-scrubbing.md) information.

The `PROCESS` [privilege](/docs/server/reference/sql-statements/account-management-sql-statements/grant.md) is required to view the table.

It has the following columns:

| CURRENT\_SCRUB\_PAGE\_NUMBER      | Page that the scrubbing thread is currently scrubbing, or NULL if not enabled.                                                       |
| CURRENT\_SCRUB\_MAX\_PAGE\_NUMBER | When a scrubbing starts rotating a table space, the field contains its current size. NULL if not enabled.                            |
| ON\_SSD                           | The field contains 1 when MariaDB detects that the table space is on a SSD based storage. 0 if not SSD or it could not be determined |
