Bridge Connectivity with Apache NiFi

Access and process 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 , NiFi can work with live data. This article describes how to connect to and query data from an Apache NiFi Flow.

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

Connecting to Data in Apache NiFi

  1. Download the CData JDBC Driver for 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.avalaraavatax.jar (and cdata.jdbc.avalaraavatax.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 .

  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:avalaraavatax:User=MyUser;Password=MyPassword;
    Database Driver Class Namecdata.jdbc.avalaraavatax.AvalaraAvataxDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.avalaraavatax.jar

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

    The primary method for performing basic authentication is to provide your login credentials, as follows:

    • User: Set this to your username.
    • Password: Set this to your password.

    Optionally, if you are making use of a sandbox environment, set the following:

    • UseSandbox: Set this to true if you are authenticating with a sandbox account.

    Authenticating Using Account Number and License Key

    Alternatively, you can authenticate using your account number and license key. Connect to data using the following:

    • AccountId: Set this to your Account Id. The Account Id is listed in the upper right hand corner of the admin console.
    • LicenseKey: Set this to your Avalara Avatax license key. You can generate a license key by logging into Avalara Avatax as an account adminstrator and navigating to Settings -> Reset License Key.
  11. Click the button to enable the new DBCPConnection Pool.

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