2667 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

    Review this. A grocery-fulfilment platform in the mould of Instacart runs an orchestrated saga over five steps - cart freeze, pricing, promotion, loyalty accrual, order creation - each with a compensating action, driven by an orchestrator with its own saga log.
