Last updated Feb 21, 2024

Idempotency is the property of a certain operation that can be applied multiple times without changing the resulting outcome by being given the same inputs. It is used in Functional Programming and was the base foundation for Functional Data Engineering.

Idempotence can be mathematically summarized as f(f(x)) =3D f(x).
