 ### Idempotent decorator
 
 For simple use cases, you can use the `idempotent` decorator on your Lambda handler function.
 
-It will treat the entire event as an idempotency key. That is, the same event will return the previously stored result within a [configurable time window](#expiring-idempotency-records) _(1 hour, by default)_.
