Enable Ask Data for Sites and Optimize Data Indexing

After a Tableau administrator enables Ask Data for a site, data source owners can optimize performance by customizing how frequently field values are indexed.

Enable or disable Ask Data for a site

As a site administrator, go to the General site settings, and do the following:

  1. (Tableau Server only) In the Web Authoring section, select Let users edit workbooks in their browser.

  2. In the Availability of Ask Data section, choose from these options:

    • Enabled enables creation of Ask Data lenses for all published data sources.

    • Disabled hides Ask Data throughout the site, while preserving information about previously created lenses so they can be restored if Ask Data is re-enabled.

Note: Beginning with version 2019.4.5, Tableau Server administrators can configure whether or not Ask Data is enabled by default.

Change data source indexing, and allow feedback to data owners

Data source owners can change how often field values are indexed for Ask Data, optimizing system performance. Data owners can also allow users to email them with questions about data structure, expected results, and more.

  1. At the top of the data source page, click the Details icon:

  2. In the Ask Data section, click Edit.

  3. Choose an indexing option for field values:

    • Automatic checks for changes every 24 hours and analyses the data source if it is live, has had an extract refreshed, or has been republished. Choose this option for a data source frequently used with Ask Data, so it will be ready before users query it.

    • Manual analyzes the data source only when users click Reindex Data Source. Choose this option if the data source changes frequently but users query it with Ask Data only occasionally.

    • Disabled analyses only field names, not values.

  4. Select Let users send feedback to data owners to let users email feedback about using the data source with Ask Data.

  5. Click Save.
