1.Integrate Anything

With TIBCO Software, you can easily integrate virtually any endpoint across your IT ecosystem with a wide variety of commercial and community developed connectors for modern business suites and platforms as well as legacy technologies. TIBCO offers 200+ connectors that are supported across the integration capabilities within TIBCO Cloud Integration: Connect, Integrate, and Develop. 

TIBCO’s broad connector portfolio allows you to focus more on developing business logic, and less on connectivity details.

1.1 Components we require for the setup

  • TIBCO ActiveMatrix BusinessWorks [Ver. 6.7.0/6.5.1]: Download
  • TIBCO ActiveMatrix BusinessWorks™ is TIBCO’s leading integration platform. It allows organizations to create, orchestrate services, capture, and publish events from internal or external applications and technologies. Developers can rapidly develop, and test graphically, integration processes in a no-code, standards based IDE. These processes are then deployed in a reliable, highly available and scalable architecture to support mission critical applications.
  • Apache Kafka [Ver. 2.6.0]: Download:Mac  A distributed streaming platform published by the Apache Foundation (see https://kafka.apache.org/), is a component of TIBCO(R) Messaging.
  • TIBCO ActiveMatrix BusinessWorks Plug-in for Apache Kafka[Ver.6.4.1] Download TIBCO ActiveMatrix BusinessWorks Plug-in for Apache Kafka integrates Apache Kafka with TIBCO ActiveMatrix BusinessWorks. It addresses the need of the TIBCO ActiveMatrix BusinessWorks customer who wants a user-friendly way to integrate with Apache Kafka to create producers, consumers and perform send message and receive message operations.
  • TIBCO Messaging-Schema Repo for Apache Kafka [Ver. 1.2.0]: Download:Mac A component of TIBCO(R) Messaging for managing Apache Avro schemas.

1.2 Apache Kafka Plug-in Palette

Activities in this palette can be used to create producers, consumers, and perform send message and receive message operations. 

  • Kafka Send Message Activity:

This activity is used to send messages to the Kafka consumer. It performs as a Kafka producer, which sends the message to a specified topic, and consumers can fetch the message from the specified topics.

  • Kafka Receive Message Activity:

This activity is a process starter activity that starts the process execution on receiving a Kafka message.

  • Avro Schema Registry:

Avro schema is used with or without registry to configure Send and Receive activities to use supplied AVRO schema as a message format.

  • Kafka Transactions:

Kafka Transactions is used to support exactly once semantics and Kafka Transaction API. 

  • Kafka Get Messages Activity:

This activity is used to consume messages from Kafka topics. The activity also allows you to seek partition offset to beginning, end or custom offset value. 

2. Architecture Overview

The following figure describes the relationship between the Apache Kafka Server, TIBCO ActiveMatrix BusinessWorksTM Plug-in for Apache Kafka, and TIBCO ActiveMatrix BusinessWorksTM

The following list describes the relationship between different products:

  • TIBCO ActiveMatrix BusinessWorksTM Plug-in for Apache Kafka communicates with the Kafka server instance.
  • TIBCO ActiveMatrix BusinessWorksTM Plug-in for Apache Kafka plugs into TIBCO ActiveMatrix BusinessWorksTM and connects to a Kafka server instance.
  • TIBCO ActiveMatrix BusinessWorksTM is an easy-to-use integration product suite for enterprise applications.
  • TIBCO Business StudioTM is the graphical user interface (GUI) used by TIBCO ActiveMatrix BusinessWorksTM and the plug-in to design business processes, and it is also the process engine used to execute them.
  • TIBCO Enterprise AdministratorTM provides a centralized administrative interface to manage and monitor the plug-in applications deployed in an enterprise.

The installer log file captures the following information: 

  • Detailed information regarding the user that invoked the installer, hostname, operating system details, and the list of assemblies installed
  • To change the location of the installer log file, specify the option -V logFile=”myLogFile” when you run the installer. 

3.3 E2E Process Flow

1.Create a Project:

  • Open the TIBCO Businessworks Studio & create BusinessWorks Application Module

2. Create a Process:

Create a process flow using Kafka activities from palette as shown

3. Create a Kafka Connection resource:

  • Populate Bootstrap Servers details in Kafka shared resource and click on ‘Validate Bootstrap Servers’ to confirm connection with Kafka Broker Server is successful.

Note: Make sure, Kafka Zookeeper & Broker Server are running in background consoles.

4. Configure Publish activity resource:

  •  Eventually, make sure both the Kafka Activities are referring to same ‘Kafka shared resource’ which we configured in the previous step.
  • In KafkaSendMessage activity, populate field Topic as ‘test’ & input message as “Hello Kafka World!!”

5. Configure Subscribe activity resource:

6. Configure Log activity:

  • Then log the incoming message from activity KafkaGetMessage

3.4 Steps to follow to test E2E Process Flow

Here are the steps to follow:

1.Execute the BW Project:

  • Start the process in debug mode as shown below,

2. Publish a Message:

  • KafkaSendMessage activity publishes message to topic ‘test’,

3. Subscribe a Message:

  • Activity KafkaGetMessage consumes the same message which is eventually getting logged in console using Log activity,
  • Also, will see the published message at Kafka server by running the following command,

 “bin/kafka-console-consumer.sh –bootstrap-server localhost:9092 –topic test —  from-beginning

5. Conclusions about Apache Kafka with TIBCO AMX BW6.x

So first, we have installed & configured TIBCO BW Kafka plugin with TIBCO AMX BW6.x & then we have developed a BW process to publish and subscribe a message to Kafka Topic ‘test’.

We have also made a consumer client listening on given Topic at Apache Kafka. When we executed a BW process, it first published a message on the Kafka topic (‘test’) using a Kafka activity, ‘Publish’.

Then we received the same message at Kafka consumer which was listening on the same topic, ‘test’. Also, the Kafka Subscribe activity in the same BW process got the same message.

This way, we can confirm, using ‘Publish’ activity, message is getting published to Kafka Topic and using ‘Subscribe’ activity, the same message can be consumed by client.
