Manage transfers

This document shows how to manage existing data transfer configurations.

You can also manually trigger an existing transfer, also known as starting a backfill run.

View your transfers

View your existing transfer configurations by viewing information about each transfer, listing all existing transfers, and viewing transfer run history or log messages.

Required roles

To get the permissions that you need to view transfer details, ask your administrator to grant you the BigQuery User (roles/bigquery.user) IAM role on the project. For more information about granting roles, see Manage access.

You might also be able to get the required permissions through custom roles or other predefined roles.

Additionally, to view log messages through Google Cloud console, you must have permissions to view Cloud Logging data. The Logs Viewer role (roles/logging.viewer) gives you read-only access to all features of Logging. For more information about the Identity and Access Management (IAM) permissions and roles that apply to cloud logs data, see the Cloud Logging access control guide.

For more information about IAM roles in BigQuery Data Transfer Service, see Access control.

Get transfer details

After you create a transfer, you can get information about the transfer's configuration. The configuration includes the values you supplied when you created the transfer, as well as other important information such as resource names.

To get information about a transfer configuration:

Console

Go to the Data transfers page.

Go to Data transfers
Select the transfer for which you want to get the details.
To see the transfer configuration and the data source details, click Configuration on the Transfer details page. The following example shows the configuration properties for a Google Ads transfer:

bq

Enter the bq show command and provide the transfer configuration's resource name. The --format flag can be used to control the output format.

bq show \
--format=prettyjson \
--transfer_config resource_name

Replace resource_name with the transfer's resource name (also referred to as the transfer configuration). If you do not know the transfer's resource name, find the resource name with: bq ls --transfer_config --transfer_location=location.

For example, enter the following command to display transfer configuration for projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7.

bq show \
--format=prettyjson \
--transfer_config projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7

API

Use the projects.locations.transferConfigs.get method and supply the transfer configuration using the name parameter.

List transfer configurations

To list all existing transfer configurations in a project:

Console

In the Google Cloud console, go to the Data transfers page.

Go to Data transfers
If there are any transfer configurations in the project, a list of the transfer configurations appears on the data transfers list.

bq

To list all transfer configurations for a project by location, enter the bq ls command and supply the --transfer_location and --transfer_config flags. You can also supply the --project_id flag to specify a particular project. If --project_id isn't specified, the default project is used. The --format flag can be used to control the output format.

To list transfer configurations for particular data sources, supply the --filter flag.

To view a particular number of transfer configurations in paginated format, supply the --max_results flag to specify the number of transfers. The command returns a page token you supply using the --page_token flag to see the next n configurations. There is a limit of 1000 configurations that will be returned if --max_results is omitted, and --max_results will not accept values greater than 1000. If your project has more than 1000 configurations, use --max_results and --page_token to iterate through them all.

bq ls \
--transfer_config \
--transfer_location=location \
--project_id=project_id \
--max_results=integer \
--filter=dataSourceIds:data_sources

Replace the following:

location is the location of the transfer configurations. The location is specified when you create a transfer.
project_id is your project ID.
integer is the number of results to show per page.
data_sources is one or more of the following:
- amazon_s3 - Amazon S3 data transfer
- azure_blob_storage - Azure Blob Storage data transfer
- dcm_dt - Campaign Manager data transfer
- google_cloud_storage - Cloud Storage data transfer
- cross_region_copy - Dataset Copy
- dfp_dt- Google Ad Manager data transfer
- adwords - Google Ads data transfer
- google_ads - Google Ads data transfer (preview)
- merchant_center - Google Merchant Center data transfer
- play - Google Play data transfer
- scheduled_query - Scheduled queries data transfer
- doubleclick_search- Search Ads 360 data transfer
- youtube_channel - YouTube Channel data transfer
- youtube_content_owner - YouTube Content Owner data transfer
- redshift - Amazon Redshift migration
- on_premises - Teradata migration

Examples:

Enter the following command to display all transfer configurations in the US for your default project. The output is controlled using the --format flag.

bq ls \
--format=prettyjson \
--transfer_config \
--transfer_location=us

Enter the following command to display all transfer configurations in the US for project ID myproject.

bq ls \
--transfer_config \
--transfer_location=us \
--project_id=myproject

Enter the following command to list the 3 most recent transfer configurations.

bq ls \
--transfer_config \
--transfer_location=us \
--project_id=myproject \
--max_results=3

The command returns a next page token. Copy the page token and supply it in the bq ls command to see the next 3 results.

bq ls \
--transfer_config \
--transfer_location=us \
--project_id=myproject \
--max_results=3 \
--page_token=AB1CdEfg_hIJKL

Enter the following command to list Ads and Campaign Manager transfer configurations for project ID myproject.

bq ls \
--transfer_config \
--transfer_location=us \

    print(f"\tID: {config.name}, Schedule: {config.schedule}")

View transfer run history

As your scheduled transfers are run, a run history is kept for each transfer configuration that includes successful transfer runs and transfer runs that fail. Transfer runs more than 90 days old are automatically deleted from the run history.

To view the run history for a transfer configuration:

Console

In the Google Cloud console, go to the Data transfers page.

Go to Data transfers
Click on the transfer in the data transfers list.
You will be on the RUN HISTORY page for the selected transfer.

bq

To list transfer runs for a particular transfer configuration, enter the bq ls command and supply the --transfer_run flag. You can also supply the --project_id flag to specify a particular project. If resource_name doesn't contain project information, the --project_id value is used. If --project_id isn't specified, the default project is used. The --format flag can be used to control the output format.

To view a particular number of transfer runs, supply the --max_results flag. The command returns a page token you supply using the --page_token flag to see the next n configurations.

To list transfer runs based on run state, supply the --filter flag.

bq ls \
--transfer_run \
--max_results=integer \
--transfer_location=location \
--project_id=project_id \
--filter=states:state, ... \
resource_name

Replace the following:

integer is the number of results to return.
location is the location of the transfer configurations. The location is specified when you create a transfer.
project_id is your project ID.
state, ... is one of the following or a comma-separated list:
- SUCCEEDED
- FAILED
- PENDING
- RUNNING
- CANCELLED
resource_name is the transfer's resource name (also referred to as the transfer configuration). If you do not know the transfer's resource name, find the resource name with: bq ls --transfer_config --transfer_location=location.

Examples:

Enter the following command to display the 3 latest runs for transfer configuration projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7. The output is controlled using the --format flag.

View transfer run details and log messages

When a transfer run appears in the run history, you can view the run details including log messages, warnings and errors, the run name, and the start and end time.

To view transfer run details:

Console

In the Google Cloud console, go to the Data transfers page.

Go to Data transfers
Click on the transfer in the data transfers list.
You will be on the RUN HISTORY page for the selected transfer.
Click on an individual run of the transfer, and the Run details panel will open for that run of the transfer.
In the Run details, note any error messages. This information is needed if you contact Cloud Customer Care. The run details also include log messages and warnings.

Modify your transfers

You can modify existing transfers by editing information on the transfer configuration, updating a user's credentials attached to a transfer configuration, and disabling or deleting a transfer.

Required roles

To get the permissions that you need to modify transfers, ask your administrator to grant you the BigQuery Admin (roles/bigquery.admin) IAM role on the project. For more information about granting roles, see Manage access.

You might also be able to get the required permissions through custom roles or other predefined roles.

Update a transfer

After you create a transfer configuration, you can edit the following fields:

Destination dataset
Display name
Any of the parameters specified for the specific transfer type
Run notification settings

You cannot edit the source of a transfer once a transfer is created.

To update a transfer:

Console

In the Google Cloud console, go to the Data transfers page.

Go to Data transfers
Click on the transfer in the data transfers list.
Click EDIT to update the transfer configuration.

bq

Enter the bq update command, provide the transfer configuration's resource name using the --transfer_config flag, and supply the --display_name, --params, --refresh_window_days, --schedule, or --target_dataset flags. You can optionally supply a --destination_kms_key flag for scheduled queries or Cloud Storage transfers.

bq update \
--display_name='NAME' \
--params='PARAMETERS' \
--refresh_window_days=INTEGER \
--schedule='SCHEDULE'
--target_dataset=DATASET_ID \
--destination_kms_key="DESTINATION_KEY" \
--transfer_config \
RESOURCE_NAME

Replace the following:

NAME: the display name for the transfer configuration.
PARAMETERS: the parameters for the transfer configuration in JSON format. For example: --params='{"param1":"param_value1"}'. The following parameters are editable:
- Campaign Manager: bucket and network_id
- Google Ad Manager: bucket and network_code
- Google Ads: customer_id
- Google Merchant Center: merchant_id
- Google Play: bucket and table_suffix
- Scheduled Query: destination_table_kms_key, destination_table_name_template, partitioning_field, partitioning_type, query, and write_disposition
- Search Ads 360: advertiser_id, agency_id, custom_floodlight_variables, include_removed_entities, and table_filter
- YouTube Channel: table_suffix
- YouTube Content Owner: content_owner_id and table_suffix
INTEGER: a value from 0 to 30. For information on setting the refresh window, see the documentation for your transfer type.
SCHEDULE: a recurring schedule, such as --schedule="every 3 hours". For a description of the schedule syntax, see Formatting the schedule.
DATASET_ID: the target dataset for the transfer configuration.
DESTINATION_KEY: the Cloud KMS key resource ID —for example, projects/project_name/locations/us/keyRings/key_ring_name/cryptoKeys/key_name. CMEK is only available for scheduled queries or Cloud Storage transfers.
RESOURCE_NAME: the transfer's resource name (also referred to as the transfer configuration). If you don't know the transfer's resource name, find the resource name with: bq ls --transfer_config --transfer_location=location.

Examples:

The following command updates the display name, target dataset, refresh window, and parameters for Google Ads transfer projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7:

bq update \

Enter the bq update command, provide the transfer configuration's resource name using the --transfer_config flag, and supply the --update_credentials flag.

bq update \
--update_credentials=boolean \
--transfer_config \
resource_name

Replace the following:

boolean is a boolean value indicating whether the credentials should be updated for the transfer configuration.
resource_name is the transfer's resource name (also referred to as the transfer configuration). If you do not know the transfer's resource name, find the resource name with: bq ls --transfer_config --transfer_location=location.

Examples:

Enter the following command to update the credentials for Google Ads transfer projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7.

bq update \
--update_credentials=true \

Disable a transfer

When you disable a transfer, disabled is added to the transfer name. When the transfer is disabled, no new transfer runs are scheduled, and no new backfills are allowed. Any transfer runs in progress are completed.

Disabling a transfer does not remove any data already transferred to BigQuery. Data previously transferred incurs standard BigQuery storage costs until you delete the dataset or delete the tables.

To disable a transfer:

Console

In the Google Cloud console, go to the BigQuery page.

Go to BigQuery
Click Transfers.
On the Transfers page, click on the transfer in the list that you want to disable.
Click on DISABLE. To re-enable the transfer, click on ENABLE.

bq

Disabling a transfer is not supported by the CLI.

API

Use the projects.locations.transferConfigs.patch method and set disabled to true in the projects.locations.transferConfig resource.

Delete a transfer

When a transfer is deleted, no new transfer runs are scheduled. Any transfer runs in progress are stopped.

Deleting a transfer does not remove any data already transferred to BigQuery. Data previously transferred incurs standard BigQuery storage costs until you delete the dataset or delete the tables.

To delete a transfer:

Console

In the Google Cloud console, go to the BigQuery page.

Go to BigQuery
Click Transfers.
On the Transfers page, click on the transfer in the list that you want to delete.
Click on DELETE. As a safety measure you will need to type the word "delete" into a box to confirm your intention.

Caution: The delete operation cannot be undone.

bq

Enter the bq rm command and provide the transfer configuration's resource name. You can use the -f flag to delete a transfer config without confirmation.

bq rm \
-f \
--transfer_config \
resource_name

Where:

resource_name is the transfer's Resource Name which is also referred to as the transfer configuration). If you do not know the transfer's Resource Name, issue the bq ls --transfer_config --transfer_location=location command to list all transfers.

For example, enter the following command to delete transfer configuration projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7.

bq rm \
--transfer_config \
projects/myproject/locations/us/transferConfigs/1234a123-1234-1a23-1be9-12ab3c456de7

API

Use the projects.locations.transferConfigs.delete method and supply the resource you're deleting using the name parameter.
