A common way to handle duplicate operations caused by retries is to carry a unique idempotency key in the request, letting the receiver determine from that key whether the same operation has already been processed, thereby safely ignoring duplicate requests.

UnverifiedTo avoid retries causing side effects to be executed repeatedly, idempotency keys or request identifiers should be used to ensure that the same logical request takes effect only once.79% similarUnverifiedIdempotency means that making multiple calls to the same operation produces exactly the same result as making it once; a unique idempotency key should be generated for each business action and the result persistently bound to that key to prevent duplicate execution.75% similarUnverifiedPOST is a non-idempotent write, and retrying after a timeout can cause duplicate creation (such as creating two orders), requiring an idempotency key or avoiding retries.72% similarUnverifiedRetries must be paired with idempotency design; otherwise, network jitter may cause duplicate order charges or repeated tool executions.71% similarUnverifiedThe basic principle of request hedging is: when a request's response time exceeds a certain threshold, the system proactively issues a duplicate request to another replica and uses whichever result returns first.70% similar
