ADMIN CANCEL DDL

The ADMIN CANCEL DDL statement allows you to cancel a running DDL job. The job_id can be found by running ADMIN SHOW DDL JOBS.

The ADMIN CANCEL DDL statement also allows you to cancel a DDL job that is committed but not yet completed executing. After the cancellation, the SQL statement that executes the DDL job returns the ERROR 8214 (HY000): Cancelled DDL job error. If you cancel 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.
