The team resolved this by progressively refactoring: first reducing transaction scope by moving billing events to async listeners, then removing unnecessary transactions entirely, and finally implementing the Transactional Outbox Pattern with Single Writer Principle. This eliminated contention between real-time and batch processing paths, trading immediate consistency for eventual consistency while achieving exactly-once semantics for billing events. ## Full article daily.dev links to this article rather than hosting it.
