minio update meta info 更新minio S3对象存储meta的实现方法
应用场景
对象存储就不多作介绍了
亚马逊，阿里云，金山云，都有相应的对象存储服务
常见的方案有ceph,minio等
amazon S3 是事实上的标准，金山云，minio都支持S3协议
通常对象存储，存一些小文件，又以互联网的媒体文件为主，例如图片，视频等等
现将大数据中的部分媒体文件迁至minio，该工作基本已全部做完
要对媒体文件，附加深度学习/机器学习算法应用ocr，语音识别等算法结果
通过sql/nosql外部存储，保存映射关系的方案就不提了，各有优缺点
缺点主要是又引入了一重依赖，复杂度相对较高，考虑在直接在meta上附加信息
因为要应用各种算法，所以为了方便对接，直接相关项目，也部分采用了python实现，以下示例全部为python，其他语言也类似
首先 minio上传文件时可以附加meta信息
