idempotency
n.a property of an action where doing it many times has the same result as doing it just once. For example, pressing a 'stop' button twice doesn't stop a machine more than pressing it once.
n.the property of certain operations in mathematics and computer science whereby they can be applied multiple times without changing the result beyond the initial application.
“The system design ensures idempotency for all payment requests.”
“In API design, idempotency is crucial because it allows a client to safely retry a request if the network connection fails.”
“Ensuring the idempotency of database transactions prevents the accidental duplication of records during high-latency periods when users might refresh their browsers repeatedly.”
Primarily used in technical contexts such as mathematics, logic, and RESTful API development.
