liuzhixin405 commented 2 years ago

in basket api basketcontroller Checkout:

var basket = await _repository.GetBasket(basketCheckout.UserName); if (basket == null) { return BadRequest(); }

        // send checkout event to rabbitmq
        var eventMessage = _mapper.Map<BasketCheckoutEvent>(basketCheckout);
        eventMessage.TotalPrice = basket.TotalPrice;
        await _publishEndpoint.Publish<BasketCheckoutEvent>(eventMessage);

        // remove the basket
        await _repository.DeleteBasket(basket.UserName);

        return Accepted();

if MassTransit publish or IBasketRepository delete fail，the checkout business is fail . can you use the transcation to achieve checkout 's atomicity ,fianlly this is comply eventual consistency, thank you!

Hi @liuzhixin405 -

Did get the resolution of question u asked? How to mention the eventual consistency in basket and Order api services? @mehmetozkaya - any idea for implementation of sage or database level distribution handling mechanism for above situation?

Thanks, Tutul
