Connect to Salesforce Data Cloud Data as an External Source in Dremio

The CData JDBC Driver for Salesforce Data Cloud implements JDBC Standards and allows various applications, including Dremio, to work with live Salesforce Data Cloud data. Dremio is a data lakehouse platform designed to empower self-service, interactive analytics on the data lake. With the CData JDBC driver, you can include live Salesforce Data Cloud data as a part of your enterprise data lake. This article describes how to connect to Salesforce Data Cloud data from Dremio as an External Source.

The CData JDBC Driver enables high-speed access to live Salesforce Data Cloud data in Dremio. Once you install the driver, authenticate with Salesforce Data Cloud and gain immediate access to Salesforce Data Cloud data within your data lake. By surfacing Salesforce Data Cloud data using native data types and handling complex filters, aggregations, & other operations automatically, the CData JDBC Driver grants seamless access to Salesforce Data Cloud data.

Prerequisites

This article assumes you are utilizing Docker to run Dremio. You can create a Docker container with the Dremio service using a command similar to the follow:

docker run -d --name dremio -p 9047:9047 -p 31010:31010 dremio/dremio-oss

Where dremio is the name of the container, 9047 is the container's port for the Dremio web interface and 31010 is the port that maps to the Dremio query service. dremio/dremio-oss specifies the image to use.

Build the ARP Connector

To use the CData JDBC Driver in Dremio, you need to build an Advanced Relation Pushdown (ARP) Connector. You can view the source code for the Connector on GitHub or download the ZIP file (GitHub.com) directly. Once you copy or extract the files, run the following command from the root directory of the connector (the directory containing the pom.xml file) to build the connector.

mvn clean install

NOTE: The CData ARP Connectors are build to be compiled with Java 11. Be sure to install Java 11 and use the correct version. You can update your Java version using a command similar to the following:

sudo update-alternatives --config java

Once the JAR file for the connector is built (in the target directory), you are ready to copy the ARP connector and JDBC Driver to your Dremio instance.

Installing the Connector and JDBC Driver

Install the ARP Connector to %DREMIO_HOME%/jars/ and the JDBC Driver for Salesforce Data Cloud to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

docker cp PATH\TO\dremio-salesforcedatacloud-plugin-{DREMIO_VERSION}.jar dremio_image_name:/opt/dremio/jars/

JDBC Driver for Salesforce Data Cloud

docker cp PATH\TO\cdata.jdbc.salesforcedatacloud.jar dremio_image_name:/opt/dremio/jars/3rdparty/

Connecting to Salesforce Data Cloud

Salesforce Data Cloud will now appear as an External Source option in Dremio. The ARP Connector built uses a JDBC URL to connect to Salesforce Data Cloud data. The JDBC Driver has a built-in connection string designer that you can use (see below).

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Salesforce Data Cloud JDBC Driver. Double-click the JAR file or execute the jar file from the command line.

java -jar cdata.jdbc.salesforcedatacloud.jar

Fill in the connection properties and copy the connection string to the clipboard.

Salesforce Data Cloud supports authentication via the OAuth standard.

OAuth

Set AuthScheme to OAuth.

Desktop Applications

CData provides an embedded OAuth application that simplifies authentication at the desktop.

You can also authenticate from the desktop via a custom OAuth application, which you configure and register at the Salesforce Data Cloud console. For further information, see Creating a Custom OAuth App in the Help documentation.

Before you connect, set these properties:

• InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• OAuthClientId (custom applications only): The Client ID assigned when you registered your custom OAuth application.
• OAuthClientSecret (custom applications only): The Client Secret assigned when you registered your custom OAuth application.

When you connect, the driver opens Salesforce Data Cloud's OAuth endpoint in your default browser. Log in and grant permissions to the application.

The driver then completes the OAuth process as follows:

• Extracts the access token from the callback URL.
• Obtains a new access token when the old one expires.
• Saves OAuth values in OAuthSettingsLocation so that they persist across connections.

For other OAuth methods, including Web Applications and Headless Machines, refer to the Help documentation.



NOTE: To use the JDBC Driver in Dremio, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

Add the Runtime Key (RTK) to the JDBC URL. You will end up with a JDBC URL similar to the following:

jdbc:salesforcedatacloud:RTK=5246...;InitiateOAuth=GETANDREFRESH

Access Salesforce Data Cloud as an External Source

To add Salesforce Data Cloud as an External Source, click to add a new source and select SalesforceDataCloud. Copy the JDBC URL and paste it into the New SalesforceDataCloud Source wizard.



Save the connection and you are ready to query live Salesforce Data Cloud data in Dremio, easily incorporating Salesforce Data Cloud data into your data lake.
