  • Tableau 2020.2 adds an improved interface for connecting to data sources hosted on Tableau Server
  • You can filter data sources by certified status, connection type and other criteria, which helps in organisations with hundreds of published sources
  • The interface shows usage statistics, such as how many times a data source has been used, to aid selection
  • The same data discovery experience is available in both Tableau Desktop and WebEdit and works virtually identically

Tableau 2020.2 introduces a faster, filterable interface for browsing published data sources on Tableau Server, making it much quicker to find the right one when an organisation has hundreds of them.

When connecting to data in Tableau Desktop or WebEdit, you often need to pick from many published data sources on Tableau Server. This feature improves that browsing and connection experience.

The Breakdown
  • Open the Tableau Server connection dialog 0:21

    From the connect/search options, choose the Tableau Server option to bring up the new data source browsing interface.

  • Filter by certified status and connection type 0:42

    Use the filtering panel on the right to narrow results down by certified or uncertified sources, connection type, or other criteria — useful when you're picking from a large catalogue of published data sources.

  • Check usage stats before connecting 1:01

    The interface shows how many times a data source has been used, which helps you judge whether it's a trustworthy, well-adopted source before connecting.

  • Same experience in WebEdit 1:21

    Creating a new workbook directly in the browser (WebEdit) opens the identical data source browsing window, with the same filtering and search options as Desktop, so you don't lose functionality working online.

Use It When

Reach for this whenever you're connecting to a Tableau Server data source in an environment with many published sources and need to quickly filter down to the certified or right one, whether you're working in Desktop or building a view directly in the browser.
