Sample code demonstrating how to use Kafka Transactions in a Spring Boot application

Read Me First

This is a sample Spring Boot application that shows how to configure Kafka Transactions support.

Getting Started

You need a running Kafka cluster before starting the application. You can use the one setup in this project. On a terminal, run:

cd kafka/ ; docker-compose up

Start the application on another terminal:

./gradlew bootRun

Monitor topic-a and topic-b:

On another terminal (for topic a)

cd kafka/

docker-compose exec broker kafka-console-consumer --bootstrap-server localhost:9092 --topic topic-a

On another terminal (for topic b)

cd kafka/

docker-compose exec broker kafka-console-consumer --bootstrap-server localhost:9092 --topic topic-b

Send messages to topic 'messages'

cd kafka/

docker-compose exec broker kafka-console-producer --broker-list localhost:9092 --topic messages
