It is used wherever strong consistency is important.

On the other hand, SAGA works sequentially, not as a single commit.

Each operation gets committed before the subsequent one, and this makes the data eventually consistent.

Thus, Saga consists of multiple steps whereas 2PC acts like a single request.

@Transactional
public class OrderService {

  @Autowired
  private SagaManager<CreateOrderSagaState> createOrderSagaManager;

  @Autowired
  private OrderRepository orderRepository;

  @Autowired
  private DomainEventPublisher eventPublisher;

  public Order createOrder(OrderDetails orderDetails) {
    ...
    ResultWithEvents<Order> orderAndEvents = Order.createOrder(...);
    Order order = orderAndEvents.result;
    orderRepository.save(order);

    eventPublisher.publish(Order.class,
                           Long.toString(order.getId()),
                           orderAndEvents.events);

    CreateOrderSagaState data =
        new CreateOrderSagaState(order.getId(), orderDetails);
    createOrderSagaManager.create(data, Order.class, order.getId());

    return order;
  }

  ...
}
