<summary>Oppure usa <code>async def</code>...</summary>

Se il tuo codice usa `async` / `await`, allora usa `async def`:

```Python hl_lines="7  12"
from fastapi import FastAPI
from typing import Optional

app = FastAPI()


@app.get("/")
async def read_root():

    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>Oder verwenden Sie <code>async def</code> ...</summary>

Wenn Ihr Code `async` / `await` verwendet, benutzen Sie `async def`:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():

def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

If your code uses `async` / `await`, use `async def`:

```Python hl_lines="9  14"

    return {"Hello": "World"}

	// On Kubernetes/Docker setups DNS resolves inappropriately sometimes

                oneWays[index] = securityResourceProvider.providePrimaryOneWayCryptographer();

## Test the setup

The next time the backup job runs, you can use the  `mc admin trace myminio` command and verify traffic is flowing to the MinIO nodes. For Veeam Backup and Replication you will need to wait for the backup to complete to the performance tier before it migrates data to the capacity tier (i.e., MinIO).

Não faz diferença. O **FastAPI** sabe o que fazer.
