ADMIN RESUME DDL JOBS

ADMIN RESUME DDL allows you to resume a paused DDL job. You can find the job_id by running ADMIN SHOW DDL JOBS.

You can use this statement to resume a paused DDL job. After the resume is completed, the SQL statement that executes the DDL job continues to show as being executed. If you try to resume a DDL job that has already been completed, you will see the DDL Job:90 not found error in the RESULT column, which indicates that the job has been removed from the DDL waiting queue.

Examples

ADMIN RESUME DDL JOBS resumes the currently paused DDL job and returns whether the job is resumed successfully.

ADMIN RESUME DDL JOBS job_id [, job_id] ...;

If the resume fails, the specific reason for the failure is displayed.

Note

During the cluster upgrade, the ongoing DDL jobs are paused, and the DDL jobs initiated during the upgrade are also paused. After the upgrade, all paused DDL jobs will resume. The pause and resume operations during the upgrade are taken automatically. For details, see TiDB Smooth Upgrade.
This statement can resume multiple DDL jobs. You can use the ADMIN SHOW DDL JOBS statement to obtain the job_id of a DDL job.
A DDL job in other status (other than paused) cannot be resumed and the resume operation will fail.
If you try to resume a job more than once, TiDB reports an error Error Number: 8261.
