Manage Downloading

For security reasons, you may need to apply controls to the ability of users to download data from the Designer Cloud Powered by Trifacta platform. You can choose the types of downloading you limit using the settings in the sections listed below.

Job Results

The Trifacta Application allows users to download their job results up to a pre-defined limit. If you set to this limit 0, job results cannot be downloaded at all from the application. When downloading job results is disabled, all job results must be downloaded outside of the Trifacta Application.

Tip

This parameter can also be used to increase the maximum size of permitted downloads from the Trifacta Application.

Note

In general, you should avoid downloading files that are larger than 1 GB in size from the Trifacta Application. Other limits, such as timeout settings, may be applied, which can cause download failures. This setting is also applied for other hard limits within the Trifacta Application, so please modify with caution. For large files, please try to download through your storage layer.

Steps:

  1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

  2. Locate the following parameter:

    "webapp.maxQueryResultsSize": 1073741824,

  3. Set the value to 0.

  4. Save your changes and restart the platform.

  5. Verify that job results cannot be downloaded. See Job Details Page.

Samples

In the Transformer page, users interact with samples of data from the entire dataset. New samples can be created as needed.

By default, samples can be downloaded to the local desktop. To disable sample downloading, please complete the following steps.

Steps:

  1. You apply this change through the Workspace Settings Page. For more information, see Platform Configuration Methods.

  2. Locate the Sample downloads parameter, and set it to disabled.

  3. To verify:

    1. Logout of the Trifacta Application. Login again.

    2. Check that the Download Sample as CSV context menu option is not available in the Recipe panel in the Transformer Page.

      Note

      Recipes can still be downloaded.

      See Recipe Panel.

Flows and Plans

For backup and migration purposes, users can be permitted to download their flow and plan definitions.

Note

A flow definition does not contain any data from the referenced datasets.

If needed, you can disable the ability to export flows and plans from the Designer Cloud Powered by Trifacta platform

Steps:

  1. You apply this change through the Workspace Settings Page. For more information, see Platform Configuration Methods.

  2. Locate the Export parameter, and set it to disabled.

  3. To verify:

    1. Logout of the Trifacta Application. Login again.

    2. Check that the context menu option for Export Flow is not available in Flow View. See Flow View Page.

Imported Datasets

The platform does not support downloading imported datasets.

Dataset previews

When you select an imported dataset, you can see a preview of the data. While no data is stored permanently on the local desktop, you may prefer to disable previews.

Note

When previews are disabled, selection of imported datasets requires that users know the contents based on filename, location, and size information.

Steps:

  1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

  2. Locate the following parameter:

    "webapp.client.previewLoadLimit": 128000,

  3. Set the value to 0.

  4. Save your changes and restart the platform.

  5. Verify that when you select a file or table to import, no preview of it is displayed. For more information, see Import Data Page.
