Presto Tableau Connector

The fastest and easiest way to connect Tableau to Presto data. Includes comprehensive high-performance data access, real-time integration, extensive metadata discovery, and robust SQL-92 support.



Use the CData Tableau Connector for Presto and Tableau Server to visualize live Presto data.

Tableau Server is a visual analytics platform transforming the way businesses use data to solve problems. When paired with the CData Tableau Connector for Presto, you get access to live Presto data within Tableau Server. This article shows how to connect to Presto in Tableau Desktop, publish a Data Source to Tableau Server, and build a simple chart from that data.

The CData Tableau Connectors enable high-speed access to live Presto data in Tableau Server. Once you install the connector, you simply authenticate with Presto and you can immediately start building responsive, dynamic visualizations and dashboards. By surfacing Presto data using native Tableau data types and handling complex filters, aggregations, & other operations automatically, CData Tableau Connectors grant seamless access to Presto data.

NOTE: The CData Tableau Connectors require Tableau 2020.3 or higher. If you are using an older version of Tableau, you will need to use the CData JDBC Driver for Presto. If you wish to connect to Presto data in Tableau Online, you will need to use CData Connect Cloud.

Enable Connectivity to Presto in Tableau Server

Start by installing the CData Tableau Connector on the machine hosting Tableau Server.

If your server is a Linux Machine:

  1. Create a directory for the connector files. For example: /opt/tableau/tableau_driver/connectors
  2. Update your Tableau configuration with the location of the directory: tsm configuration set -k native_api.connect_plugins_path -v /opt/tableau/tableau_driver/connectors --force-keys
  3. Copy cdata.presto.taco and cdata.tableau.presto.lic from the connector installation directory.
  4. Place the copies in the directory created above.
  5. Restart Tableau Server.

If your server is a Windows Machine:

  1. Create a directory for the connector files. For example: C:\Program Files\Tableau\Connectors
  2. Update your Tableau configuration with the location of the directory: tsm configuration set -k native_api.connect_plugins_path -v C:\Program Files\Tableau\Connectors --force-keys
  3. Copy cdata.presto.taco and cdata.tableau.presto.lic from the connector installation directory.
  4. Place the copies in the directory created above.
  5. Restart Tableau Server.

Next, install the CData Tableau Connector on the machine running Tableau Desktop. The connector will be installed to the correct location automatically.

Connect to Presto in Tableau Desktop

Once the connectors are installed on the Server machine, we can configure a connection to Presto in Tableau Desktop and publish a Presto-based Data Source to Tableau Server.

  1. Open Tableau Desktop.
  2. Click More under Connect -> To a Server.
  3. Select "Presto by CData".
  4. Configure the connection to the data.

    Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

    To enable TLS/SSL, set UseSSL to true.

    Authenticating with LDAP

    In order to authenticate with LDAP, set the following connection properties:

    • AuthScheme: Set this to LDAP.
    • User: The username being authenticated with in LDAP.
    • Password: The password associated with the User you are authenticating against LDAP with.

    Authenticating with Kerberos

    In order to authenticate with KERBEROS, set the following connection properties:

    • AuthScheme: Set this to KERBEROS.
    • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
    • KerberosRealm: The Kerberos Realm used to authenticate the user with.
    • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
    • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
    • User: The user who is authenticating to Kerberos.
    • Password: The password used to authenticate to Kerberos.
  5. Click "Sign In".

Discover Schemas and Query Data

Once you establish the connection to Presto data, you can configure which entities to visualize.

  1. Select CData from the Database pull-down menu.
  2. Select Presto from the Schema pull-down menu.
  3. Drag the tables and views you wish to visualize onto the join area. You can include multiple tables.
  4. Select Update Now or Automatically Update. Update Now lets you preview the first 10,000 rows of the data source (or enter the number of rows you want to see in the Rows text box). Automatically Update auto-loads the changes in the preview area.

Publish Data to Tableau Server

After you configure the data you wish to visualize, you can publish the Data Source to a Tableau Server instance. In Tableau Desktop:

  1. Click Server -> Sign In.
  2. Enter the URL for your Tableau Server.
  3. Authenticate with Tableau Server credentials.
  4. Click Server -> Publish Data Source and select your data source.
  5. Click Publish.
  6. Select the Project, name the Data Source, and optionally add a description.
  7. Click Publish.

This creates a new entry under the server's data source list, from which you an change the data source's permissions, view its history, and perform other management tasks.

Note that workstation connected to the same server will be able to use the same source in Tableau Desktop, even if the connector isn't installed there. Also, workbooks created directly on Tableau Server (via the web interface) can use this source.

Visualize Presto Data in Tableau Server

With the Data Source published to Tableau Server, you are ready to visualize Presto data.

  1. Login to your Tableau Server instance.
  2. Connect to the remote source using the Search for Data -> Tableau Server in the Connect sidebar.
  3. Click the published Data Source.
  4. Click New Workbook.
  5. In the workbook, Presto fields are listed as Dimensions and Measures, depending on the data type. The CData Tableau Connector discovers data types automatically, allowing you to leverage the powerful data processing and visualization features of Tableau.
  6. Drag a field from the Dimensions or Measures area to Rows or Columns. Tableau creates column or row headers.
  7. Select one of the chart types from the Show Me tab. Tableau displays the chart type that you selected.
