 Prefect provides a few ways to work with cached data between tasks or flows. In-memory caching of task **inputs** is automatically applied by the Prefect pipeline to optimize retries or other times when Prefect can anticipate rerunning the same task in the future. Users can also configure to cache the **output** of a prior run of a task and use it as the output of a future run of that task or even as the output of a run of a different task.
 
 Out of the box, Prefect Core does not persist cached data in a permanent fashion. All data, results, _and_ cached states are only stored in memory within the
