idempotencyallowing
Idempotencyallowing is a term used to describe design practices and mechanisms that enable operations to be executed multiple times with the same effect as a single execution. It addresses the reliability challenge in distributed systems where retries, network failures, or duplicates can lead to unintended side effects. The goal is to make repeated invocations idempotent, so the system state remains unchanged after the initial application.
Core techniques include idempotency keys, which attach a unique token to a request and cause the server
In practice idempotencyallowing is widely used in web APIs, payment gateways, and message processing. For example,
Implementation considerations include storage for keys and results, key expiration policies, and the window during which
Relation to HTTP: many operations are inherently idempotent by method (GET, PUT, DELETE), and idempotency keys
