Connect to TigerGraph Data and Transfer Data in Talend

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

Connect to TigerGraph in Talend as a JDBC Data Source

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

1. Add a new database connection to TigerGraph 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 authenticate with your TigerGraph instance, set the User, Password, and URL properties to valid TigerGraph credentials. By default connections are made on port 14240.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.tigergraph.jar

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

   A typical JDBC URL is below:

   jdbc:tigergraph:User=MyUserName;Password=MyPassword;URL=MyURL;
4. Enter the path to the cdata.jdbc.tigergraph.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 Person Table to a Flat File

You can follow the procedure below to transfer the person 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 person tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
