Before you begin, please review the following prerequisites.


The name of the service account used by the product is provided by Google and cannot be modified.


If domain restricted sharing has been enabled as a policy in your enterprise, you must add a trust policy for the Alteryx GSuite domain. If you do not have the ID for this domain, it can be provided by Alteryx Support.

Review Org policy

The Google Cloud Platform enables a wide range of organization policies, which can determine default behaviors across projects and services. Before you begin, you should review your organization policies. In particular, please review the following organization policy:

Disable Automatic IAM Grants for Default Service Accounts

This policy limits products and services that are enabled in a project from gaining access to the default service accounts that they need to work within the Google Cloud Platform. These service accounts must be managed using finer-grained controls within the enterprise.

When disabled:

  • Dataprep by Trifacta can use the two required service agents in any project where the product is enabled.

  • These service agents are:

    • Dataprep Service Agent: manages design time interactions between Dataprep by Trifacta and Google Cloud Platform

    • Compute Engine Service Account: manages runtime product interactions with Dataflow

When enabled:

  • You must manually assign these service agents or create them from scratch.


For effective use of Dataprep by Trifacta, it is recommended that you disable the above organization policy, at least while you are creating projects for use with the product.

For more information, see Google Service Account Management.

Set up a project

To use either product edition, you must have the following already set up in the Google Cloud Platform.

This staging bucket is used for staging assets for use on Dataflow jobs and is required for use with the product. If you do have permissions to create a storage bucket in the U.S, you do not need to create a storage bucket for staging and can skip to the next section.


If you do not have permissions to create a Cloud Storage bucket in the U.S., you must your own staging bucket before enabling Dataprep by Trifacta in your project. This name of this bucket must begin with the following text string: dataprep-staging- followed by an identifying value.
