Build SingleStore Visualizations in Tableau Desktop



Use CData Connect Cloud to connect to live SingleStore data and build visualizations in Tableau.

Tableau is a visual analytics platform transforming the way businesses use data to solve problems. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to SingleStore data for visualizations, dashboards, and more. This article shows how to connect to SingleStore and build visualizations from SingleStore data in Tableau.

CData Connect Cloud provides a pure SQL Server, cloud-to-cloud interface for SingleStore, allowing you to easily build visualizations from live SingleStore data in Tableau without installing connectors. As you build visualizations, Tableau generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to SingleStore, leveraging server-side processing to quickly return SingleStore data.

Configure SingleStore Connectivity for Tableau

Connectivity to SingleStore from Tableau is made possible through CData Connect Cloud. To work with SingleStore data from Tableau, we start by creating and configuring a SingleStore connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "SingleStore" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to SingleStore.

    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.
  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add SingleStore Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to SingleStore data from Tableau.

Visualize Live SingleStore Data in Tableau

To establish a connection from Tableau Desktop to the CData Connect Cloud Virtual SQL Server API, follow these steps.

  1. In Tableau Desktop, open a new book. Under To a Server, select More, then Microsoft SQL Server.
  2. Enter your credentials:
    • Server: enter the Virtual SQL Server endpoint and port separated by a comma: tds.cdata.com,14333
    • Database: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, SingleStore1).
    • Authentication: select Use a specific username and password.
    • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
    • Password: enter the PAT you previously generated.
    • Require SSL: leave this selected.
  3. Click Sign In.
  4. Select the Database (Connect Cloud connection) you wish to work with and opt for a Live or Extract Connection type.
  5. Select the table(s) you wish to visualize. If you select multiple tables, define the relationship between the tables using the appropriate columns.
  6. Select the fields to visualize.

Real-Time Access to SingleStore Data from Data Applications

At this point, you have a direct, cloud-to-cloud connection to live SingleStore data from your Tableau workbook. You can create new visualizations, build dashboards, and more.
