Martin Fowler Idempotent Receiver: Building Resilient Distributed Systems Without Data Duplication

"In the complex world of distributed systems and microservices, ensuring that a message is processed exactly once remains one of the most significant challenges for engineers. Network failures, timeout issues, and system crashes often result in the same message being sent multiple times. To solve this, the martin fowler idempotent receiver pattern has become a cornerstone of reliable software architecture.When a system sends a command or a notification, it expects a predictable outcome. However, in a distributed environment, "at-least-once" delivery is the standard. This means a receiver must be prepared to handle duplicate messages without ca..."
