Build Spark-Connected Visualizations in datapine

datapine is a browser-based business intelligence platform. When paired with the CData Connect Cloud, you get access to your Spark data directly from your datapine visualizations and dashboards. This article describes connecting to Spark in CData Connect Cloud and building a simple Spark-connected visualization in datapine.

CData Connect Cloud provides a pure SQL Server interface for Spark, allowing you to query data from Spark without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Spark, leveraging server-side processing to return the requested Spark data quickly.

Configure Spark Connectivity for datapine

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

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

   Set the Server, Database, User, and Password connection properties to connect to SparkSQL.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Spark 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.
