Connect to HPCC Systems Data in HULFT Integrate

Connect to HPCC Systems 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 HPCC Systems, HULFT Integrate can work with live HPCC Systems data. This article walks through connecting to HPCC Systems 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 HPCC Systems data. When you issue complex SQL queries to HPCC Systems, the driver pushes supported SQL operations, like filters and aggregations, directly to HPCC Systems 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 HPCC Systems data using native data types.

Enable Access to HPCC Systems

To enable access to HPCC Systems data from HULFT Integrate projects:

  1. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.hpcc.jar (and cdata.jdbc.hpcc.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 HPCC Systems Data

Once you copy the JAR files, you can create a project with access to HPCC Systems 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.: HPCCtoCSV)

Once you create the project, add components to the script to copy HPCC Systems 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 HPCC Systems. Set the following properties:
    • Name: HPCC Systems Connection Settings
    • Driver class name: cdata.jdbc.hpcc.HPCCDriver
    • URL: jdbc:hpcc:URL=http://127.0.0.1:8510;User=test;password=xA123456;Version=1;Cluster=hthor;

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.hpcc.jar

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

      To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

      Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

      Set Cluster to the target cluster.

  2. Write your SQL statement. For example:
    SELECT CustomerName, Price FROM hpcc::test::orders
  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. hpcc::test::orders.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 HPCC Systems 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 HPCC Systems data into a CSV file.
