Use CData Connect Cloud to create a virtual SQL Server Database for Elasticsearch 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 Elasticsearch data for visualizations, dashboards, and more. This article shows how to create a virtual database for Elasticsearch and build visualizations from Elasticsearch data in Tableau Online.

CData Connect Cloud provides a pure SQL Server, cloud-to-cloud interface for Elasticsearch, allowing you to easily build visualizations from live Elasticsearch 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 Elasticsearch, leveraging server-side processing to quickly return Elasticsearch data.

Create a Virtual SQL Server Database for Elasticsearch 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 "Elasticsearch" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Elasticsearch.

    Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

    The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

    Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

  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 Elasticsearch Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Elasticsearch 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 Microsoft SQL Server Connector from the data wizard and fill in the values for your Connect Cloud instance.
    NOTE: Be sure to check the "Require SSL" checkbox.
  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 Elasticsearch Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Elasticsearch 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.
