Then for any subsequent call of `get_settings()` in the dependencies for the next requests, instead of executing the internal code of `get_settings()` and creating a new `Settings` object, it will return the same object that was returned on the first call, again and again.

#### `lru_cache` Technical Details

However, some applications do not utilize Service readiness (connecting directly to the pod, etc).
Additionally, eventually consistency means we will often get some final requests trickle in before all clients are aware the Pod is shutting down.

Finally, we SHOULD tell our (HBONE) peers we are shutting down.
This can help ensure that clients do not hold onto pooled connections for too long.

#### Define a *path operation decorator*

{* ../../docs_src/first_steps/tutorial001.py hl[6] *}

The `@app.get("/")` tells **FastAPI** that the function right below is in charge of handling requests that go to:

* the path `/`
* using a <abbr title="an HTTP GET method"><code>get</code> operation</abbr>

/// info | "`@decorator` Info"

That `@something` syntax in Python is called a "decorator".
