Idempotency
A property of operations in distributed systems whereby executing the same operation multiple times produces the same effect on system state as executing it once. It is commonly used to ensure the reliability of API calls and message processing.

Idempotency means that executing the same operation once and executing it multiple times produces the same impact on the system state, and it is crucial in scenarios such as refunds, order placement, and transfers.
An idempotent update means that when the system receives a request with the same identifier, it does not create a new record but instead overwrites or updates the existing record.
Retries must be paired with idempotency design; otherwise, network jitter may cause duplicate order charges or repeated tool executions.
