Connect to Azure Synapse Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Azure Synapse into your processes in RapidMiner. This article uses the CData JDBC Driver for Azure Synapse to transfer Azure Synapse data to a process in RapidMiner.

Connect to Azure Synapse in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Azure Synapse:

1. Add a new database driver for Azure Synapse: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL:

   jdbc:azuresynapse:
   

4. Enter the path to the cdata.jdbc.azuresynapse.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   cdata.jdbc.azuresynapse.AzureSynapseDriver
   

   👁 The JDBC driver configuration. (Salesforce is shown.)
   
6. Create a new Azure Synapse connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Azure Synapse driver you configured previously.
9. Enter your connection string in the Host box.

   Connecting to Azure Synapse

   In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:

   • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
   • Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.

   Authenticating to Azure Synapse

   Connect to Azure Synapse using the following properties:

   • User: The username provided for authentication with Azure.
   • Password: The password associated with the authenticating user.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Azure Synapse JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.azuresynapse.jar
   

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

   A typical connection string is below:

   User=myuser;Password=mypassword;Server=localhost;Database=Northwind;
   

10. Enter your username and password if necessary. 👁 The connection to the JDBC data source. (Salesforce is shown.)
    

You can now use your Azure Synapse connection with the various RapidMiner operators in your process. To retrieve Azure Synapse data, drag the Retrieve operator from the Operators view. 👁 A Retrieve operation to select data. (Salesforce is shown.)
With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Azure Synapse data.
