Connect to Azure Data Catalog as a JDBC data source in HULFT Integrate

HULFT Integrate is a modern data integration platform that provides a drag-and-drop user interface to create cooperation flows, data conversion, and processing so that complex data connections are easier than ever to execute. When paired with the CData JDBC Driver for Azure Data Catalog, HULFT Integrate can work with live Azure Data Catalog data. This article walks through connecting to Azure Data Catalog and moving the data into a CSV file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Azure Data Catalog data. When you issue complex SQL queries to Azure Data Catalog, the driver pushes supported SQL operations, like filters and aggregations, directly to Azure Data Catalog 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 Azure Data Catalog data using native data types.

Enable Access to Azure Data Catalog

To enable access to Azure Data Catalog data from HULFT Integrate projects:

  1. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.azuredatacatalog.jar (and cdata.jdbc.azuredatacatalog.lic), to the jdbc_adapter subfolder for the Integrate Server
  2. Restart the HULFT Integrate Server and launch HULFT Integrate Studio

Build a Project with Access to Azure Data Catalog Data

Once you copy the JAR files, you can create a project with access to Azure Data Catalog data. Start by opening Integrate Studio and creating a new project.

  1. Name the project
  2. Ensure the "Create script" checkbox is checked
  3. Click Next
  4. Name the script (e.g.: AzureDataCatalogtoCSV)

Once you create the project, add components to the script to copy Azure Data Catalog data to a CSV file.

Configure an Execute Select SQL Component

Drag an "Execute Select SQL" component from the Tool Palette (Database -> JDBC) into the Script workspace.

  1. In the "Required settings" tab for the Destination, click "Add" to create a new connection for Azure Data Catalog. Set the following properties:
    • Name: Azure Data Catalog Connection Settings
    • Driver class name: cdata.jdbc.azuredatacatalog.AzureDataCatalogDriver
    • URL: jdbc:azuredatacatalog:InitiateOAuth=GETANDREFRESH

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.azuredatacatalog.jar

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

      You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

        CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

      Connect Using OAuth Authentication

      You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

  2. Write your SQL statement. For example:
    SELECT DslAddressDatabase, Type FROM Tables
  3. Click "Extraction test" to ensure the connection and query are configured properly
  4. Click "Execute SQL statement and set output schema"
  5. Click "Finish"

Configure a Write CSV File Component

Drag a "Write CSV File" component from the Tool Palette (File -> CSV) onto the workspace.

  1. Set a file to write the query results to (e.g. Tables.csv)
  2. Set "Input data" to the "Select SQL" component
  3. Add columns for each field selected in the SQL query
  4. In the "Write settings" tab, check the checkbox to "Insert column names into first row"
  5. Click "Finish"

Map Azure Data Catalog Fields to the CSV Columns

Map each column from the "Select" component to the corresponding column for the "CSV" component.

Finish the Script

Drag the "Start" component onto the "Select" component and the "CSV" component onto the "End" component. Build the script and run the script to move Azure Data Catalog data into a CSV file.
