## Architecture

### Environment variables

#### MINIO_ETCD_ENDPOINTS

This is comma separated list of etcd servers that you want to use as the MinIO federation back-end. This should
be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

これで、このクラスを使用して依存関係を宣言することができます。

**FastAPI** は`CommonQueryParams`クラスを呼び出します。これにより、そのクラスの「インスタンス」が作成され、インスタンスはパラメータ`commons`として関数に渡されます。

## 型注釈と`Depends`

上のコードでは`CommonQueryParams`を２回書いていることに注目してください:

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

以下にある最後の`CommonQueryParams`:

```Python
... = Depends(CommonQueryParams)
```
