Managing jobs

After you submit a BigQuery job, you can view job data, list jobs, cancel a job, or rerun a job.

When a job is submitted, it can be in one of three states:

• PENDING: scheduled
• RUNNING
• DONE: reported as SUCCESS or FAILURE (if the job completed with errors)

Viewing job data

You can view job data and metadata by using the Cloud Console, the classic web UI, command-line interface, and API. This data includes details such as the job type, the job state, and the user who ran the job.

Required permissions

At a minimum, in order to get job data and metadata, you must be granted bigquery.jobs.get permissions. The following predefined IAM role includes bigquery.jobs.get permissions:

• bigquery.admin

If you grant an account the bigquery.admin role, the user can view all job data in the project no matter who submitted the job.

The following roles are granted bigquery.jobs.get permissions for self-created jobs. These users can only view job data for jobs they submit:

• bigquery.user
• bigquery.jobUser

For more information on IAM roles and permissions in BigQuery, see Access control.

Viewing information about jobs

To view information about a job:

Console

1. In the navigation pane, click Job history, or click Query history to see information about query jobs.

2. Click Personal history to view details about your jobs. Click Project history to view details about all jobs run in the project.

Classic UI

1. In the navigation pane, click Job History, or click Query history to see information about query jobs.

2. In the Recent Jobs section, click the job to view the details. For query jobs, click the Query history tab to view query job details.

bq

Issue the bq show command with the -j flag and the job id parameter.

When you supply the job ID, you can use the fully qualified ID or the short form. For example, job IDs listed in the BigQuery web UI are fully qualified, that is, they include the project and location:

my-project-1234:US.bquijob_123x456_123y123z123c

Job IDs in the command-line tool are listed using the short form. Project ID and location are not included:

bquijob_123x456_123y123z123c

To specify the job location, supply the --location flag and set the value to your location. This flag is optional if you use the fully qualified job ID. If you include the --location flag and you're using the fully qualified job ID, the --location flag is ignored.

The following command requests information about a job:

bq --location=location show -j job_id

Where:

• location is optional. Location is the name of the location where the job runs. For example, if you are using BigQuery in the Tokyo region, set the flag's value to asia-northeast1. You can set a default value for the location using the .bigqueryrc file.
• job_id is the ID of the job.

Examples:

The following command gets summary information about job US.bquijob_123x456_123y123z123c running in myproject.

bq show -j myproject:US.bquijob_123x456_123y123z123c

The output looks like the following:

 Job Type    State      Start Time      Duration      User Email       Bytes Processed   Bytes Billed   Billing Tier   Labels
 ---------- --------- ----------------- ---------- ------------------- ----------------- -------------- -------------- --------
 extract    SUCCESS   06 Jul 11:32:10   0:01:41    [e-mail]

To see full job details, enter:

bq show --format=prettyjson -j myproject:US.bquijob_123x456_789y123z456c

The output looks like the following:

API

Call jobs.get and provide the jobId and projectId parameters. (Optional) Supply the location parameter and set the value to the location where the job runs. This parameter is optional if you use the fully qualified job ID that includes the location, for example, my-project-1234:US.bquijob_123x456_123y123z123c.

Listing jobs in a project

Your project maintains your job history for all jobs created in the past six months.

You can view your BigQuery job history by:

• Using the Google Cloud Console or the classic web UI
• Using the command-line interface
• Calling the jobs.list API method
• Using the client libraries

The job history includes jobs that are in the RUNNING state and jobs that are DONE (indicated by reporting the state as SUCCESS or FAILURE).

Required permissions

At a minimum, to list jobs, you must be granted bigquery.jobs.list permissions. The following predefined IAM roles include bigquery.jobs.list permissions:

• bigquery.user
• bigquery.admin

The following role is granted bigquery.jobs.list permissions only for self-created jobs. Entities granted this role can only list jobs they submit:

• bigquery.jobUser

When you are granted bigquery.jobs.list permissions, you can list all jobs in a project, but the details and metadata are redacted for jobs submitted by other users. bigquery.jobs.list permissions lets you see full details for self-created jobs.

To list all jobs, including details for jobs created by other users, you must be granted bigquery.jobs.listAll permissions. Only the bigquery.admin role has bigquery.jobs.listAll permissions.

For more information on IAM roles and permissions in BigQuery, see Predefined roles and permissions.

Listing jobs

When you list jobs in a project, you do not need to provide a location. Currently, jobs are listed for all locations.

To list jobs in a project:

Console

1. In the navigation pane, click Job History.

2. In the Personal history section, your jobs are listed by creation time with the most recent jobs at the top. The list includes jobs only for the current user. To see all jobs for a project, click Project history. (If you aren't the project owner you may not have permission to view all jobs for a project.)

Classic UI

1. In the navigation pane, click Job History.

2. In the Recent Jobs section, your jobs are listed by creation time with the most recent jobs at the top. The list includes jobs only for the current user. To see all jobs, use the command-line tool or the API.

bq

Issue the bq ls command with one of the following flags:

• -j is used to identify jobs as the resource to list.
• --all or -a lists jobs from all users. To see full (unredacted) details for all jobs, you must have bigquery.jobs.listAll permissions.
• --min_creation_time is used to list jobs after a supplied timestamp value.
• --max_creation_time is used ot list jobs before a supplied timestamp value.
• -n limits the results. By default, you are limited to 100,000 results.

bq ls -j -a \
--min_creation_time integer1 \
--max_creation_time integer2 \
-n integer3 \
project_id

Where:

• integer1 is an integer that represents a timestamp.
• integer2 is an integer that represents a timestamp.
• integer3 is an integer that indicates the number of jobs returned.
• project_id is the ID of the project that contains the jobs you're listing. If you set a default project, you do not need to provide the project_id parameter.

Examples:

The following command lists all jobs for the current user. Running this command requires bigquery.jobs.list permissions.

bq ls -j myproject

The following command lists all jobs for all users. Running this command requires bigquery.jobs.listAll permissions.

bq ls -j -a myproject

The following command lists the 10 most recent jobs in myproject:

bq ls -j -a -n 10 myproject

The following command lists all jobs submitted before Oct 18, 2018, at 4:04:53 PM. This timestamp (in milliseconds) is equivalent to the following integer value: 1539903893000.

bq ls -j --max_creation_time 1539903893000

API

Call jobs.list and provide the projectId parameter. To list jobs for all users, set the allUsers parameter to true. Setting allUsers to true requires bigquery.jobs.listAll permissions.

Canceling jobs

You can cancel a RUNNING or PENDING job by:

• Using the Cloud Console or the classic web UI
• Using the command-line interface
• By calling the jobs.cancel API method
• Using the client libraries

Note that not all job types can be canceled. If the job cannot be canceled, an error is returned.

Even if the job can be canceled, success is not guaranteed. The job might have completed by the time the cancel request is submitted, or the job might be in a stage where it cannot be canceled.

Note: You can still incur costs after canceling a job depending on the stage at which it was canceled. For more information, see the Pricing page.

Required permissions

At a minimum, to cancel a job, you must be granted bigquery.jobs.update permissions. The following predefined IAM role includes bigquery.jobs.update permissions:

• bigquery.admin

If you grant an account the bigquery.admin role, the user can cancel any eligible job, no matter who submitted it.

The following roles can cancel self-created jobs. These users can only cancel jobs they submit:

• bigquery.user
• bigquery.jobUser

For more information on IAM roles and permissions in BigQuery, see Predefined roles and permissions.

Canceling a job

To cancel a job:

Console

1. In the navigation pane, click Job history.

2. In the Personal history section, click the job you're canceling. The most recent jobs appear at the top of the list.

3. In the job details, click Cancel job.

Classic UI

1. In the navigation pane, click Job History.

2. In the Recent Jobs section, click the job you're canceling. The most recent jobs appear at the top of the list.

3. In the job details, click Cancel Job.

   

bq

Issue the bq cancel command with the job_id parameter. You can request cancellation and return immediately by using the --nosync flag. By default, cancellation requests wait for completion.

When you supply the job ID, you can use the fully qualified ID or the short form. For example, job IDs listed in the BigQuery web UI are fully qualified, that is, they include the project and location:

my-project-1234:US.bquijob_123x456_123y123z123c

Job IDs in the command-line tool are listed using the short form. Project ID and location are not included:

bquijob_123x456_123y123z123c

To specify the job location, supply the --location flag and set the value to your location. This flag is optional if you use the fully qualified job ID. If you include the --location flag and you're using the fully qualified job ID, the --location flag is ignored.

The following command requests job cancellation and waits for completion. If the fully qualified job ID is supplied, the --location flag is ignored:

bq --location=location cancel job_id

The following command requests job cancellation and returns immediately. If the fully qualified job ID is supplied, the --location flag is ignored:

bq --location=location --nosync cancel job_id

Where:

• location is optional. Location is the name of the location where the job runs. For example, if you are using BigQuery in the Tokyo region, set the flag's value to asia-northeast1. You can set a default value for the location using the .bigqueryrc file.
• job_id is the ID of the job you're canceling. If you copy the job ID from the BigQuery web UI, the project ID and location are included in the job ID. For example, my-project-1234:US.bquijob_123x456_123y123z123c.

Examples:

The following command cancels job my-project-1234:US.bquijob_123x456_123y123z123c running in the US multi-region location in my-project-1234 and waits for completion. Because the fully qualified job ID is used, the location flag is not supplied.

bq cancel my-project-1234:US.bquijob_123x456_123y123z123c

The following command cancels job bquijob_123x456_123y123z123c running in the US multi-region location in my-project-1234 and waits for completion. Because the short form of the job ID is used, the --location flag is supplied.

bq --location=US cancel bquijob_123x456_123y123z123c

The following command cancels job bquijob_123x456_123y123z123c running in the US multi-region location in my-project-1234 and returns immediately. Because the fully qualified job ID is used, the --location flag is not supplied.

bq --nosync cancel my-project-1234:US.bquijob_123x456_123y123z123c

Repeating a job

It is not possible to rerun a job using the same job ID. Instead you create a new job with the same configuration. When you submit the new job in the Cloud Console, the classic web UI, or the command-line interface, a new job ID is assigned. When you submit the job using the API or client libraries, you must generate a new job ID.
