Added in version 2020.4.1

Install and Deploy Tableau Prep Builder

CPU requirement update

Beginning with version 2020.4, Tableau requires you to have CPUs that support SSE4.2 and POPCNT instruction sets. These CPUs have been common for more than 10 years and are installed on most newer computers. Tableau products are also not currently compatible with Apple Silicon processors.

If you attempt to install or upgrade Tableau on a computer that does not support these instruction sets or that uses the Apple Silicon processors, the installer will not allow you to continue.

To see a complete list of supported technologies, see tableau.com/techspecs(Link opens in a new window).

Tableau Prep on the Web

Starting in version 2020.4.1, you can now create flows to clean and prepare your data using either Tableau Prep Builder, Tableau Server, or Tableau Online. The Data Management Add-on is not required unless you want to schedule your flows to run using Tableau Prep Conductor.

You can connect to your data, build a new flow or edit an existing flow and your work is automatically saved every few seconds as you go. Create draft flows that are only available to you or publish your flow to make it available for others. Run your individual flows right from the web or run your flows automatically on a schedule using Tableau Prep Conductor.

While most features in Tableau Prep Builder will also be available when building and editing flows on the web, some features and connectors may not be available. For more information, see Tableau Prep on the Web.

Connect to Data

Support for connector plugins

When Tableau Prep doesn't provide a built-in connector for your data, you can now connect to ODBC- and JDBC-based data using connector plugins created with the Tableau Connector SDK, just like Tableau Desktop. Connector plugins are supported when connecting to data in Tableau Prep Builder and on the web in Tableau Server.

Note: Connector plugins that use Connection Dialog v2 are not yet supported.

To use connector plugins, download the connector .taco file, and add it to the following directories:

  • Tableau Prep Builder:
    • Windows: C:\Users\[Windows User]\Documents\My Tableau Prep Repository\Connectors
    • MacOS: /Users/[user]/Documents/My Tableau Prep Repository/Connectors
  • Tableau Server (Flow web authoring): [Tableau_Server_Installation_Directory]/data/tabsvc/flowqueryservice/Connectors
  • Tableau Server (Tableau Prep Conductor): [Tableau_Server_Installation_Directory]/data/tabsvc/flowprocessor/Connectors

For more information about connector plugins, see Use connector plugins to connect to ODBC- and JDBC-based data (version 2020.4.1 and later).

Connect to spatial data

You can now connect to, clean and shape spatial files data in Tableau Prep both in Tableau Prep Builder and when creating flows on the web. With this feature, you can:

  • Connect to Spatial File formats
    • Tableau Prep Builder: Esri Shapefiles, Esri File Geodatabases, KML, TopoJSON, GeoJSON, extracts, MapInfo MID/MIF, TAB files and zipped shapefiles.
    • Tableau Server and Tableau Online: Zipped shapefiles, KML, TopoJSON, GeoJSON, Esri File Geodatabases and extracts.
  • Connect to spatial databases (Amazon Redshift, Microsoft SQL Server, Oracle and PostgreSQL).
  • Combine spatial tables with non-spatial tables using standard joins.
  • Output spatial data to an extract (.hyper) file.

Spatial functions, spatial joins through intersects, and visualising spatial data on a map view in Tableau Prep is not currently supported. For more information about connecting to spatial data, see Connect to Spatial files and databases (version 2020.4.1 and later).
