level, unlike other object storage vendors. This allows applications to choose different storage class by setting `x-amz-storage-class=STANDARD/REDUCED_REDUNDANCY` for each object uploads so effectively utilizing the capacity of the cluster. Additionally these can also be enforced using IAM policies to make sure the client uploads with correct HTTP headers.

- MinIO also supports expansion of existing clusters in server pools. Each pool is a self contained entity with same SLA's (read/write quorum)...

如果主文件是 `main.py`，则用以下 `uvicorn` 命令运行主应用：

そして、チュートリアルと同様な方法でアプリケーションを起動して下さい。ただし、以下の様に`--reload` オプションは使用しないで下さい:

```console
