Why do we use saga patterns?

Comment

Use the Saga pattern when you need to: Ensure data consistency in a distributed system without tight coupling.

Roll back or compensate if one of the operations in the sequence fails.

@Configuration
public class EventConsumerConfig {

    @Autowired
    private OrderStatusUpdateHandler handler;


    @Bean
    public Consumer<PaymentEvent> paymentEventConsumer(){
        //listen payment-event-topic
        //will check payment status
        //if payment status completed -> complete the order
        //if payment status failed -> cancel the order
        return (payment)-> handler.updateOrder(payment.getPaymentRequestDto().getOrderId(),po->{
            po.setPaymentStatus(payment.getPaymentStatus());
        });
    }
}
