Stream Adobe Target Data into Apache Kafka Topics

Apache Kafka is an open-source stream processing platform that is primarily used for building real-time data pipelines and event-driven applications. When paired with the CData JDBC Driver for Adobe Target, Kafka can work with live Adobe Target data. This article describes how to connect, access and stream Adobe Target data into Apache Kafka Topics and to start Confluent Control Center to help users secure, manage, and monitor the Adobe Target data received using Kafka infrastructure in the Confluent Platform.

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

Prerequisites

Before connecting the CData JDBC Driver for streaming Adobe Target data in Apache Kafka Topics, install and configure the following in the client Linux-based system.

1. Confluent Platform for Apache Kafka
2. Confluent Hub CLI Installation
3. Self-Managed Kafka JDBC Source Connector for Confluent Platform

Define a New JDBC Connection to Adobe Target data

1. Download CData JDBC Driver for Adobe Target on a Linux-based system
2. Follow the given instructions to create a new directory extract all the driver contents into it:
   1. Create a new directory named Adobe Target

      		mkdir AdobeTarget
      		

   2. Move the downloaded driver file (.zip) into this new directory

      		mv AdobeTargetJDBCDriver.zip AdobeTarget/
      		

   3. Unzip the CData AdobeTargetJDBCDriver contents into this new directory

      		unzip AdobeTargetJDBCDriver.zip
      		

3. Open the Adobe Target directory and navigate to the lib folder

   ls
   cd lib/
   

4. Copy the contents of the lib folder of the CData JDBC Driver for Adobe Target into the lib folder of Kafka Connect JDBC. Check the Kafka Connect JDBC folder contents to confirm that the cdata.jdbc.adobetarget.jar file is successfully copied into the lib folder

   cp -r /path/to/CData JDBC Driver for Adobe Target/lib/* /usr/share/confluent-hub-components/confluentinc-kafka-connect-jdbc/lib/
   cd /usr/share/confluent-hub-components/confluentinc-kafka-connect-jdbc/lib/
   

5. Install the CData Adobe Target JDBC driver license using the given command, followed by your Name and Email ID

   	java -jar cdata.jdbc.adobetarget.jar -l
   	

6. Enter the product key or "TRIAL" (In the scenarios of license expiry, please contact our CData Support team)
7. Start the Confluent local services using the command:

   	confluent local services start
   	

   This starts all the Confluent Services like Zookeeper, Kafka, Schema Registry, Kafka REST, Kafka CONNECT, ksqlDB and Control Center. You are now ready to use the CData JDBC driver for Adobe Target to stream messages using Kafka Connect Driver into Kafka Topics on ksqlDB.

   
8. Create the Kafka topics manually using a POST HTTP API Request:

    curl --location 'server_address:8083/connectors' 
   	--header 'Content-Type: application/json'
   	--data '{ 
   		"name": "jdbc_source_cdata_adobetarget_01", 
   		"config": { 
   			"connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector", 
   			"connection.url": "jdbc:adobetarget:Tenant=mycompanyname;InitiateOAuth=GETANDREFRESH;",
   		"topic.prefix": "adobetarget-01-", 
   		"mode": "bulk" 
   		} 
   	}'
   

   Let us understand the fields used in the HTTP POST body (shown above):

   • connector.class: Specifies the Java class of the Kafka Connect connector to be used.
   • connection.url: The JDBC connection URL to connect with Adobe Target data.

     Built-in Connection String Designer

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

     		java -jar cdata.jdbc.adobetarget.jar
     		

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

     To connect to Adobe Target, you must provide the Tenant property along with OAuth connection properties mentioned below. Note that while other connection properties can influence processing behavior, they do not affect the ability to connect.

     To determine your Tenant name:

     1. Log in to Adobe Experience. The URL will look similar to: "https://experience.adobe.com/#/@mycompanyname/preferences/general-section".
     2. Extract the value after the "/#/@". In this example, it is "mycompanyname".
     3. Set the Tenant connection property to that value.

     User Accounts (OAuth)

     You must set AuthScheme to OAuthClient for all user account flows.

     Note: Adobe authentication via OAuth requires updating your token every two weeks.

     All Applications

     CData provides an embedded OAuth application that simplifies OAuth authentication. Alternatively, you can create a custom OAuth application. Review Creating a Custom OAuth App in the Help documentation for more information.

     Obtaining the OAuth Access Token

     Set the following properties to connect:

     • InitiateOAuth: Set to GETANDREFRESH to automatically perform the OAuth exchange and refresh the OAuthAccessToken as needed.
     • OAuthClientId : Set to the client Id assigned when you registered your app.
     • OAuthClientSecret : Set to the client secret assigned when you registered your app.
     • CallbackURL : Set to the redirect URI defined when you registered your app. For example: https://localhost:3333

     With these settings, the provider obtains an access token from Adobe Target, which it uses to request data. The OAuth values are stored in the location specified by OAuthSettingsLocation, ensuring they persist across connections.

     
   • topic.prefix: A prefix that will be added to the Kafka topics created by the connector. It's set to "adobetarget-01-".
   • mode: Specifies the mode in which the connector operates. In this case, it's set to "bulk", which suggests that the connector is configured to perform bulk data transfer.

   This request adds all the tables/contents from Adobe Target as Kafka Topics.

   Note: The IP Address (server) to POST the request (shown above) is the Linux Network IP Address.

9. Run ksqlDB and list the topics. Use the commands:

   ksql
   list topics;
   

   
10. To view the data inside the topics, type the SQL Statement:

    PRINT topic FROM BEGINNING;
    

Connecting with the Confluent Control Center

To access the Confluent Control Center user interface, ensure to run the "confluent local services" as described in the above section and type http://<server address>:9021/clusters/ on your local browser.
