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

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

Connecting to Confluence Data in Apache NiFi

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

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:confluence:User=admin;APIToken=myApiToken;Url=https://yoursitename.atlassian.net;Timezone=America/New_York;
    Database Driver Class Name	cdata.jdbc.confluence.ConfluenceDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.confluence.jar

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

    Obtaining an API Token

    An API token is necessary for account authentication. To generate one, login to your Atlassian account and navigate to API tokens > Create API token. The generated token will be displayed.

    Connect Using a Confluence Cloud Account

    To connect to a Cloud account, provide the following (Note: Password has been deprecated for connecting to a Cloud Account and is now used only to connect to a Server Instance.):

    • User: The user which will be used to authenticate with the Confluence server.
    • APIToken: The API Token associated with the currently authenticated user.
    • Url: The URL associated with your JIRA endpoint. For example, https://yoursitename.atlassian.net.

    Connect Using a Confluence Server Instance

    To connect to a Server instance, provide the following:

    • User: The user which will be used to authenticate with the Confluence instance.
    • Password: The password which will be used to authenticate with the Confluence server.
    • Url: The URL associated with your JIRA endpoint. For example, https://yoursitename.atlassian.net.
11. Click the button to enable the new DBCPConnection Pool.

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