Bridge Teradata Connectivity with Apache NiFi

Access and process Teradata data in Apache NiFi using the CData JDBC Driver.

Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. When paired with the CData JDBC Driver for Teradata, NiFi can work with live Teradata data. This article describes how to connect to and query Teradata data from an Apache NiFi Flow.

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

Connecting to Teradata Data in Apache NiFi

  1. Download the CData JDBC Driver for Teradata installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.teradata.jar (and cdata.jdbc.teradata.lic), to the Apache NiFi lib subfolder, for example, C:\nifi-1.3.0-bin\nifi-1.3.0\lib.

    On Windows, the default location for the CData JDBC Driver is C:\Program Files\CData\CData JDBC Driver for Teradata.

  3. Start Apache NiFi. For example:

    cd C:\nifi-1.3.0-bin\nifi-1.3.0\bin
    run-nifi.bat
    
  4. Navigate to the Apache NiFi UI in your web browser: typically http://localhost:8080/nifi
  5. Click the (Configuration) button from the Operate sidebar.
  6. In the NiFi Flow Configuration page, navigate to the Controller Services tab.
  7. Click the button to create a new controller service.
  8. In the Add Controller Service page, select DBCPConnection Pool, and then click Add.
  9. Click the gear button to configure the new DBCPConnection Pool.
  10. In the Configure Controller Service page, navigate to the Properties tab. Fill in the properties:

    PropertyValue
    Database Connection URLjdbc:teradata:User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;
    Database Driver Class Namecdata.jdbc.teradata.TeradataDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.teradata.jar

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

    To connect to Teradata, provide authentication information and specify the database server name.

    • User: Set this to the username of a Teradata user.
    • Password: Set this to the password of the Teradata user.
    • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
    • Port: Specify the port the server is running on.
    • Database: Specify the database name. If not specified, the default database is used.
  11. Click the button to enable the new DBCPConnection Pool.

Your Teradata data is now available for use in Apache NiFi. For example, you can use the DBCPConnection Pool as the source for a QueryDatabaseTable processor.
