Publish SingleStore-Connected Dashboards in Tableau Server



Use CData Tableau Connectors and Tableau Server to visualize live SingleStore 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 SingleStore, you get access to live SingleStore data within Tableau Server. This article shows how to connect to SingleStore 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 SingleStore data in Tableau Server. Once you install the connector, you simply authenticate with SingleStore and you can immediately start building responsive, dynamic visualizations and dashboards. By surfacing SingleStore data using native Tableau data types and handling complex filters, aggregations, & other operations automatically, CData Tableau Connectors grant seamless access to SingleStore 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 Tableau Connector for SingleStore. If you wish to connect to SingleStore data in Tableau Cloud, you will need to use CData Connect Cloud.

Enable Connectivity to SingleStore in Tableau Server

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

Installation on a Linux Machine:

  1. Unpack the setup.zip archive. Creating a directory for the connector like /opt/cdata/singlestore is recommended, but the exact install location does not matter.
  2. Navigate to the lib subdirectory under the install directory. Generate a license file by running this command and following the prompts: java -jar cdata.tableau.singlestore.jar -l
  3. Copy cdata.tableau.singlestore.jar and cdata.tableau.singlestore.lic into the drivers directory, /opt/tableau/tableau_driver/jdbc.
  4. Copy cdata.singlestore.taco into the connectors directory, MyTableauServerRootDir/data/tabsvc/vizqlserver/Connectors. In most cases MyTableauServerRootDir is located at /var/opt/tableau/tableau_server.
  5. Restart Tableau Server.

If you cannot execute the java commmand from step 2, you will need to install a Java runtime environment. The name of this package differs on Red Hat-based and Debian-based systems:

OSJava Package
Ubuntuopenjdk-8-jre-headless
Debianopenjdk-8-jre-headless
RHELjava-1.8.0-openjdk
CentOSjava-1.8.0-openjdk
Fedorajava-1.8.0-openjdk
SUSEjava-1_8_0-openjdk

You can substitute Java 8 with a later Java release as needed.

Installation on a Windows Machine:

  1. Run the setup.exe installer. The driver JAR file will be automatically placed in the drivers directory, C:\Program Files\Tableau\Drivers.
  2. Navigate to the lib folder under the installation directory. By default the installation directory is a folder in C:\Program Files\CData.
  3. Copy cdata.tableau.singlestore.lic into the drivers directory.
  4. Copy cdata.tableau.singlestore.taco into the connectors directory, MyTableauServerRootDir/data/tabsvc/vizqlserver/Connectors. In most cases MyTableauServerRootDir is located under C:\ProgramData.
  5. Restart Tableau Server.

Connect to SingleStore in Tableau Desktop

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

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

    The following connection properties are required in order to connect to data.

    • Server: The host name or IP of the server hosting the SingleStore database.
    • Port: The port of the server hosting the SingleStore database.
    • Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

    Connect Using Standard Authentication

    To authenticate using standard authentication, set the following:

    • User: The user which will be used to authenticate with the SingleStore server.
    • Password: The password which will be used to authenticate with the SingleStore server.

    Connect Using Integrated Security

    As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.

    Connect Using SSL Authentication

    You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:

    • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
    • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
    • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
    • SSLClientCertType: The certificate type of the client store.
    • SSLServerCert: The certificate to be accepted from the server.

    Connect Using SSH Authentication

    Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

    • SSHClientCert: Set this to the name of the certificate store for the client certificate.
    • SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
    • SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
    • SSHClientCertType: The certificate type of the client store.
    • SSHPassword: The password that you use to authenticate with the SSH server.
    • SSHPort: The port used for SSH operations.
    • SSHServer: The SSH authentication server you are trying to authenticate against.
    • SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
    • SSHUser: Set this to the username that you use to authenticate with the SSH server.
  5. Click "Sign In".

Discover Schemas and Query Data

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

  1. Select CData from the Database pull-down menu.
  2. Select SingleStore 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 SingleStore Data in Tableau Server

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