Bridge Reckon Connectivity with Apache NiFi

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

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

Connecting to Reckon Data in Apache NiFi

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

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:

    Property	Value
    Database Connection URL	jdbc:reckon:User=RCUser;Password=RCUserPassword;URL=http://remotehost:8166;
    Database Driver Class Name	cdata.jdbc.reckon.ReckonDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.reckon.jar

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

    When you are connecting to a local Reckon instance, you do not need to set any connection properties.

    Requests to Reckon are made through the Remote Connector. The Remote Connector runs on the same machine as Reckon and accepts connections through a lightweight, embedded Web server. The server supports SSL/TLS, enabling users to connect securely from remote machines.

    The first time you connect to your company file, you will need to authorize the Remote Connector with Reckon. See the "Getting Started" chapter of the help documentation for a guide.

11. Click the button to enable the new DBCPConnection Pool.

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