This article describes how to connect Tableau to a Presto database and set up the data source.
Tableau connects to Presto 141t from Teradata and to Presto on-premises and Amazon EMR Presto instances for Presto version 0.148.
Before you begin, gather this connection information:
Name of the server that hosts the database you want to connect to
Note: LDAP authentication is available from Tableau Desktop version 10.3.2 forward.
Sign-in credentials. Your choices depend on the authentication method you choose, and can include the following:
Are you connecting to an SSL server?
(Optional) Initial SQL statement to run every time Tableau connects
This connector requires a driver to talk to the database. You might already have the required driver installed on your computer. If the driver is not installed on your computer, Tableau displays a message in the connection dialog box with a link to the Driver Download(Link opens in a new window) page where you can find driver links and installation instructions.
Note: If you are connecting to PrestoDB, download the appropriate driver from the PrestoDB page. If you are connecting to Trino, (previously PrestoSQL), download the appropriate driver from the Trino page. The Trino driver only works in Tableau versions 2021.3, 2021.2.2, 2021.1.5, 2020.4.8, 2020.3.12, and above.
Start Tableau and under Connect, select Presto. For a complete list of data connections, select More under To a Server. Then do the following:
Enter the name of the server you want to connect to.
Enter the catalog name.
Select the Authentication method: Username or LDAP, and enter the credentials you're prompted for.
Select the Require SSL check box when connecting to an SSL server.
(Optional) Select Initial SQL to specify a SQL command to run at the beginning of every connection, such as when you open the workbook, refresh an extract, sign in to Tableau Server, or publish to Tableau Server. For more information, see Run Initial SQL.
Select Sign In.
If Tableau can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact your network administrator or database administrator.
On the data source page, do the following:
(Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to.
From the Schema drop-down list, select the search icon or enter the schema name in the text box and select the search icon, and then select the schema.
In the Table text box, select the search icon or enter the table name and select the search icon, and then select the table.
Drag the table to the canvas, and then select the sheet tab to start your analysis.
Use custom SQL to connect to a specific query rather than the entire data source. For more information, see Connect to a Custom SQL Query.
If you use Tableau Desktop on a Mac, when you enter the server name to connect, use a fully qualified domain name, such as mydb.test.ourdomain.lan, instead of a relative domain name, such as mydb or mydb.test.
Alternatively, you can add the domain to the list of Search Domains for the Mac computer so that when you connect, you need to provide only the server name. To update the list of Search Domains, go to System Preferences > Network > Advanced, and then open the DNS tab.
