Use CData Connect Cloud to create a virtual MySQL Database for SFTP data and build visualizations in Tableau Online.

Tableau Online is an analytics platform fully hosted in the cloud. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to SFTP data for visualizations, dashboards, and more. This article shows how to create a virtual database for SFTP and build visualizations from SFTP data in Tableau Online.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for SFTP, allowing you to easily build visualizations from live SFTP data in Tableau Online without installing connectors or publishing worksheets and data sources from Tableau Desktop. As you build visualizations, Tableau Online 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 SFTP, leveraging server-side processing to quickly return SFTP data.

Create a Virtual MySQL Database for SFTP Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Cloud and click Databases.
  2. Select "SFTP" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to SFTP.

    SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.

    Set the following connection properties to control the relational view of the file system:

    • RemotePath: Set this to the current working directory.
    • TableDepth: Set this to control the depth of subfolders to report as views.
    • FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.
    Stored Procedures are available to download files, upload files, and send protocol commands. See gdatamodel for more on using SQL to interact with the server.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to build visualizations in Tableau Online.

Visualize Live SFTP Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual SFTP database in Connect Cloud and building a simple visualization from the data.

  1. Log into Tableau Online, select a project, and create a new workbook.
  2. In the new workbook, choose the MySQL Connector from the data wizard and fill in the values for your Connect Cloud instance.
  3. Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINed tables as needed).
  4. Select Dimensions and Measures and configure your visualization.

SQL Access to SFTP Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live SFTP data from your Tableau Online workbook. You can create new visualizations, build dashboards, and more, with no need to publish data sources and workbooks from Tableau Desktop.
