Connect to TigerGraph Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for TigerGraph into your processes in RapidMiner. This article uses the CData JDBC Driver for TigerGraph to transfer TigerGraph data to a process in RapidMiner.

Connect to TigerGraph in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for TigerGraph: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL: jdbc:tigergraph:
4. Enter the path to the cdata.jdbc.tigergraph.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class: cdata.jdbc.tigergraph.TigerGraphDriver
6. Create a new TigerGraph connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the TigerGraph driver you configured previously.
9. Enter your connection string in the Host box.

   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 connection string is below:

   User=MyUserName;Password=MyPassword;URL=MyURL;
10. Enter your username and password if necessary.

You can now use your TigerGraph connection with the various RapidMiner operators in your process. To retrieve TigerGraph data, drag the Retrieve operator from the Operators view. With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the TigerGraph data.
