Information Schema INNODB_TABLESPACES_SCRUBBING Table

MariaDB 10.1.3 - 10.5.1

InnoDB and XtraDB data scrubbing was introduced in MariaDB 10.1.3. The table was removed in MariaDB 10.5.2 - see MDEV-15528.

The Information Schema INNODB_TABLESPACES_SCRUBBING table contains data scrubbing information.

The PROCESS privilege is required to view the table.

It has the following columns:

Column	Description
`SPACE`	InnoDB table space id number.
`NAME`	Path to the table space file, without the extension.
`COMPRESSED`	The compressed page size, or zero if uncompressed.
`LAST_SCRUB_COMPLETED`	Date and time when the last scrub was completed, or `NULL` if never been performed.
`CURRENT_SCRUB_STARTED`	Date and time when the current scrub started, or `NULL` if never been performed.
`CURRENT_SCRUB_ACTIVE_THREADS`	Number of threads currently scrubbing the tablespace.
`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.
