* 따라서 이미지, 동영상, 큰 이진코드와 같은 대용량 파일들을 많은 메모리를 소모하지 않고 처리하기에 적합합니다.
* 업로드 된 파일의 메타데이터를 얻을 수 있습니다.
* [file-like](https://docs.python.org/3/glossary.html#term-file-like-object) `async` 인터페이스를 갖고 있습니다.
* file-like object를 필요로하는 다른 라이브러리에 직접적으로 전달할 수 있는 파이썬 [`SpooledTemporaryFile`](https://docs.python.org/3/library/tempfile.html#tempfile.SpooledTemporaryFile) 객체를 반환합니다.

### `UploadFile` { #uploadfile }

`UploadFile` has the following `async` methods. They all call the corresponding file methods underneath (using the internal `SpooledTemporaryFile`).

			objects = madmin.Objects{Count: dataUsageInfo.ObjectsTotalCount}
			versions = madmin.Versions{Count: dataUsageInfo.VersionsTotalCount}
			deleteMarkers = madmin.DeleteMarkers{Count: dataUsageInfo.DeleteMarkersTotalCount}
			usage = madmin.Usage{Size: dataUsageInfo.ObjectsTotalSize}
		} else {
			buckets = madmin.Buckets{Error: err.Error()}
			objects = madmin.Objects{Error: err.Error()}

### v1.1+

Version 1.1 added inline data, which will be placed after the metadata.

Therefore, the metadata is wrapped as a binary array for easy skipping.
