Some of the important concepts are:

* Security - HTTPS
* Running on startup
* Restarts
* Replication (the number of processes running)
* Memory
* Previous steps before starting

We'll see how they would affect **deployments**.

                            # TODO: remove when deprecating Pydantic v1
                            {

                            }

                    },

Sie können den (HTTP-)`status_code` definieren, den die Response Ihrer *Pfadoperation* verwenden soll.

Sie können direkt den `int`-Code übergeben, etwa `404`.

Aber falls Sie sich nicht mehr erinnern, wofür jede Nummer steht, können Sie die Abkürzungs-Konstanten in `status` verwenden:

=== "Python 3.10+"

    ```Python hl_lines="1  15"
    {!> ../../../docs_src/path_operation_configuration/tutorial001_py310.py!}
    ```

You can adapt it to any other NoSQL database like:

* **MongoDB**
* **Cassandra**
* **CouchDB**
* **ArangoDB**
* **ElasticSearch**, etc.

`await` が機能するためには、非同期処理をサポートする関数内にある必要があります。これは、`async def` で関数を宣言するだけでよいです:

```Python hl_lines="1"
async def get_burgers(number: int):
    # ハンバーガーを作成するために非同期処理を実行
    return burgers
```

...`def` のかわりに:

```Python hl_lines="2"
# 非同期ではない
def get_sequential_burgers(number: int):
    # ハンバーガーを作成するためにシーケンシャルな処理を実行
    return burgers
```
