Process & Analyze Suadeo Data in Databricks (AWS)

Databricks is a cloud-based service that provides data processing capabilities through Apache Spark. When paired with the CData JDBC Driver, customers can use Databricks to perform data engineering and data science on live Suadeo data. This article explains how to host the CData JDBC Driver in AWS, as well as connect to and process live Suadeo data in Databricks.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Suadeo data. When you issue complex SQL queries to Suadeo, the driver pushes supported SQL operations, like filters and aggregations, directly to Suadeo and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Suadeo data using native data types.

Install the CData JDBC Driver in Databricks

To work with live Suadeo data in Databricks, install the driver on your Databricks cluster.

1. Navigate to your Databricks administration screen and select the target cluster.
2. On the Libraries tab, click "Install New."
3. Select "Upload" as the Library Source and "Jar" as the Library Type.
4. Upload the JDBC JAR file (cdata.jdbc.suadeo.jar) from the installation location (typically C:\Program Files\CData[product_name]\lib).

Access Suadeo Data in your Notebook: Python

With the JAR file installed, we are ready to work with live Suadeo data in Databricks. Start by creating a new notebook in your workspace. Name the notebook, select Python as the language (though Scala is available as well), and choose the cluster where you installed the JDBC driver. When the notebook launches, we can configure the connection, query Suadeo, and create a basic report.

Configure the Connection to Suadeo

Connect to Suadeo by referencing the JDBC Driver class and constructing a connection string to use in the JDBC URL. Additionally, you will need to set the property in the JDBC URL (unless you are using a Beta driver). You can view the licensing file included in the installation for information on how to set this property.

Step 1: Connection Information

driver = "cdata.jdbc.suadeo.SuadeoDriver"
url = "jdbc:suadeo:RTK=5246...;URL=https://mysuadeoinstance;User=username;Password=password;AuthenticationName=your_auth_name;"

Built-in Connection String Designer

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

java -jar cdata.jdbc.suadeo.jar

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

The driver uses the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant to authenticate to Suadeo. Authentication occurs directly using your credentials; there is no browser-based authorization flow or refresh token.

Set the following connection properties:

• URL: The base URL of your Suadeo instance.
• User: Your Suadeo username.
• Password: Your Suadeo password.
• AuthenticationName: The name identifier for the authentication configuration in your Suadeo instance. Different authentication names can be configured for different environments or use cases.

When you connect, the driver sends your credentials to the Suadeo OAuth token endpoint, receives an access token, and uses it for all subsequent requests. A new access token is obtained automatically when needed during the session.

Load Suadeo Data

Once you configure the connection, you can load Suadeo data as a dataframe using the CData JDBC Driver and the connection information.

Step 2: Reading the data

remote_table = spark.read.format ( "jdbc" ) \
	.option ( "driver" , driver) \
	.option ( "url" , url) \
	.option ( "dbtable" , "Customers") \
	.load ()

Display Suadeo Data

Check the loaded Suadeo data by calling the display function.

Step 3: Checking the result

display (remote_table.select ("Id"))

Analyze Suadeo Data in Databricks

If you want to process data with Databricks SparkSQL, register the loaded data as a Temp View.

Step 4: Create a view or table

remote_table.createOrReplaceTempView ( "SAMPLE_VIEW" )

With the Temp View created, you can use SparkSQL to retrieve the Suadeo data for reporting, visualization, and analysis.

% sql

SELECT Id, Name FROM SAMPLE_VIEW ORDER BY Name DESC LIMIT 5

👁 Displaying Suadeo Data

The data from Suadeo is only available in the target notebook. If you want to use it with other users, save it as a table.

remote_table.write.format ( "parquet" ) .saveAsTable ( "SAMPLE_TABLE" )
