Connect to HPCC Systems Data and Transfer Data in Talend

Integrate HPCC Systems data with standard components and data source configuration wizards in Talend Open Studio.

This article shows how you can easily integrate the CData JDBC driver for HPCC Systems into your workflow in Talend. This article uses the CData JDBC Driver for HPCC Systems to transfer HPCC Systems data in a job flow in Talend.

Connect to HPCC Systems in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to HPCC Systems:

  1. Add a new database connection to HPCC Systems data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
  2. In the resulting wizard, enter a name for the connection.
  3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

    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.

    Built-in Connection String Designer

    For assistance in 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.

    A typical JDBC URL is below:

    jdbc:hpcc:URL=http://127.0.0.1:8510;User=test;password=xA123456;Version=1;Cluster=hthor;
  4. Enter the path to the cdata.jdbc.hpcc.jar file, located in the lib subfolder of the installation directory.
  5. Right-click the connection and then click Retrieve Schema.
  6. Click Next with the default options to select the tables you want to import.
  7. Finish the wizard with the default options.

Output the Hpcc::test::orders Table to a Flat File

You can follow the procedure below to transfer the hpcc::test::orders table to a flat file output component:

  1. In the Table Schemas node, drag the tables to the workspace.
  2. In the dialog that is displayed, select the tJDBCInput component.
  3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
  4. Right-click the hpcc::test::orders tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
