Added in version 2021.2.1

Einstein Discovery

Einstein Discovery prediction enhancements in Tableau Prep Builder and on the web

Beginning with Tableau Server version 2021.2, you can now bring prediction models built in Einstein Discovery directly into your Prep flows on the web. Just like in Tableau Prep Builder version 2021.1.3, you can sign into Einstein Discovery, choose from deployed models, and apply them to your flow data.

If you need to access models on different Einstein Discovery servers, you are no longer restricted to one server instance per flow. Now you can sign into multiple Einstein Discovery servers to choose the models you need both on Tableau Prep Builder and on the web.

For more information, see Add Einstein Discovery Predictions to your flow.

Connect to Data

Connect to data using SharePoint Lists

If your data is stored in a Microsoft SharePoint list, you can now connect to this data source using the SharePoint Lists connector. For more information about connecting to your data source using this connector, see SharePoint Lists(Link opens in a new window) in the Tableau Desktop help.

Connect to data sources that include user filters when authoring flows on the web

Starting in Tableau Server and Tableau Online version 2021.2, you can now connect to published data sources that include user filters or functions. When you connect to published data sources that include user filters or functions, the published data source access is authorised based on the identity of the user signed into the server, and only the data that the user is allowed to see is returned.

For more information about connecting to published data sources, see Connect to published data sources.

Clean and Shape Data

Rename fields in bulk

Use the new Rename Fields option to quickly find and replace, remove, add prefixes or suffixes to multiple values at once.

In prior releases you had to manually change each field name one at a time. Now you can select the new Rename Fields option in the toolbar and a new pane opens enabling you to select the fields you want to change, and apply field name changes in bulk.

Replace or remove text or add a prefix or suffix to all fields that match your search criteria in a single click. You can also automatically apply this same change to new fields that are added when your data is refreshed. Just tick the Automatically rename new fields box when making your changes.

For more information, see Rename fields in bulk.

Save and Share your Work

Write output in Google BigQuery table format

You can now choose to write flow output in the form of a Google BigQuery table, allowing Google BigQuery to read the data directly. Tableau Prep can write up to 2 GB as output to the table.

For more information, see Save flow output data to external databases.
