CANCEL JOB |
The CANCEL JOB statement stops long-running jobs. |
true |
The CANCEL JOB
statement lets you stop long-running jobs, which include IMPORT
jobs, enterprise BACKUP
and RESTORE
jobs, schema changes, user-created table statistics jobs, automatic table statistics jobs, and changefeeds.
When an enterprise RESTORE
is canceled, partially restored data is properly cleaned up. This can have a minor, temporary impact on cluster performance.
Only members of the admin
role can cancel a job. By default, the root
user belongs to the admin
role.
Parameter | Description |
---|---|
job_id |
The ID of the job you want to cancel, which can be found with SHOW JOBS . |
select_stmt |
A selection query that returns job_id (s) to cancel. |
> SHOW JOBS;

+----------------+---------+-------------------------------------------+...
> CANCEL JOB 27536791415282;
To cancel multiple jobs, nest a SELECT
clause that retrieves job_id
(s) inside the CANCEL JOBS
statement:
{% include copy-clipboard.html %}
> CANCEL JOBS (SELECT job_id FROM [SHOW JOBS]
WHERE user_name = 'maxroach');
All jobs created by maxroach
will be cancelled.
Canceling an automatic table statistics job is not useful since the system will automatically restart the job immediately. To permanently disable automatic table statistics jobs, disable the sql.stats.automatic_collection.enabled
cluster setting:
{% include copy-clipboard.html %}
> SET CLUSTER SETTING sql.stats.automatic_collection.enabled = false;
