Introduction to Event-Driven Architectures and Idempotency
The Rise of Event-Driven Architectures
Modern e-commerce systems often depend on event-driven architectures to ensure scalability and responsiveness. For instance, when a user places an order, events like “Order Placed,” “Payment Processed,” and “Inventory Updated” are triggered asynchronously.
Why Idempotency Matters in Distributed Systems
In distributed systems, events can be duplicated or retried due to network failures, leading to problems like duplicate orders or incorrect inventory adjustments. Idempotency ensures that processing an event multiple times yields the same result as processing it once.
