Producers

Producer classes help in pushing data from the application to kafka topics. For this, we have a custom implementation of KafkaTemplate class in our tracer library called CustomKafkaTemplate. This implementation of producer class does not change across services of DIGIT. Producer implementation can be viewed here - Producer Implementation

Now, for adding producer support in this guide, the following steps need to be followed -

i) Update tracer version in pom.xml to 2.0.0-SNAPSHOT

ii) Create a producer folder and add a new class to it by the name of Producer. Add the following code the this class -

@Service
@Slf4j
public class Producer {

    @Autowired
    private CustomKafkaTemplate<String, Object> kafkaTemplate;

    public void push(String topic, Object value) {
        kafkaTemplate.send(topic, value);
    }
}
