Trifacta Dataprep


On April 28, 2021, Google is changing the required permissions for attaching IAM roles to service accounts. If you are using IAM roles for your Google service accounts, please see Changes to User Management.


Feature Availability: This feature is available in the following editions:

  • Cloud Dataprep Premium by TRIFACTA® INC.
  • Cloud Dataprep Standard by TRIFACTA INC.
  • Cloud Dataprep Legacy by TRIFACTA INC.


Cloud Dataprep by TRIFACTA INC. is a third-party service integrated with the Google Cloud Platform. This section describes the requirements for enabling the product and how to disable it in your projects if needed.

Enable Dataprep

After it is authorized, Cloud Dataprep by TRIFACTA INC. only accesses project data when permitted by the user in the following ways:

  • Browse and preview project data
  • Read project data into  Cloud Dataprep by TRIFACTA INC. for transformation purposes
  • Write results of jobs back to the project
  • Attach service accounts in your project to Cloud Dataflow jobs used for transformation.

All project data is read from and written to user-owned projects.

NOTE:  No BigQuery or Cloud Storage data is stored by Cloud Dataprep by TRIFACTA INC. or by Trifacta.

Google Cloud Storage bucket

When  Cloud Dataprep by TRIFACTA INC. is enabled in your project, Google creates a  Google Cloud Storage bucket for you. Your project is automatically provisioned to use this bucket. 

NOTE: This bucket is created by Google and is not under the control of Trifacta. It is associated with a specific project.

NOTE: This bucket is created in a region within the United States.

During enablement in the project, you may receive a Failed: Create bucket error. If your enterprise permissions do not permit the creation of a bucket in the United States, then please create a bucket with the following naming convention:


The designation information can be any accepted value.

Dataprep service and roles

To enable access, Google Cloud Console creates a service account that belongs to the Cloud Dataprep by TRIFACTA INC. service and supplies it with read/write access to Cloud Dataflow, Google Cloud Storage, and BigQuery in the Google Cloud project. For more information, see Dataprep Roles→dataprep.serviceAgent.

IAM service accounts. The roles/dataprep.serviceAgent role that is granted during product activation includes the roles/iam.serviceAccountUser role. This role enables access to all service accounts in the project, including service accounts that may be created in the future.

For more information, see Required Dataprep User Permissions.

Launch Dataprep

After the project owner has enabled Cloud Dataprep by TRIFACTA INC. for a project, users who are granted the roles/dataprep.user role for the project can access the product.

When a user launches the product in a project for the first time, the user must complete the following:

  1. Log in to a Google account.
  2. Accept the Terms of Service.
  3. Choose a  Google Cloud Storage bucket to use with the product.

For each project to which you have access, these steps must be performed the first time that you access the product.

Disable Dataprep

Disabling Cloud Dataprep by TRIFACTA INC. is not reversible. You cannot undo this operation.

  • Disabling services used by Cloud Dataprep by TRIFACTA INC. triggers the removal of all Cloud Dataflow assets from the product.
  • All is permanently deleted and cannot be retrieved.
  • Services used by Cloud Dataprep by TRIFACTA INC. include (and not limited to) Cloud Dataflow and Compute Engine.

Disable Dataprep for a project

When  Cloud Dataprep by TRIFACTA INC. is disabled in a project, it is disabled for all users in a project. If a project owner disables Cloud Dataprep by TRIFACTA INC.:

  • Each project user retains access to data (including transformed data) stored within user-owned Google Cloud projects (for example, raw or transformed data stored in Cloud Storage or BigQuery)
  • Cloud Dataprep by TRIFACTA INC. can no longer access project data, and users can no longer view or transform project data through the product.
  • All metadata associated with the product is deleted. This deletion is immediate and is automatically performed by Trifacta; Google never touches this metadata. This metadata includes:
    • recipes for transforming data, settings, and rules
    • jobs run on project data before Dataprep was disabled (including filenames/descriptions of data)

NOTE: If you have provided Cloud Dataprep by TRIFACTA INC. with access to datasets or resources outside of the current project, disabling the product does not remove those permissions. Those permissions must be removed manually. For more information, see

NOTE: Disabling is permanent and irreversible.
