阿里MAXCOMPUTE数据专辑信息读取并同步数据表

阿里MAXCOMPUTE数据专辑信息读取并同步数据表

在阿里云大数据体系中,我们可以使用数据地图的数据专辑,对数据的类别等进行一个管理

那么管理后的数据,我们想要落表进行相关的数据分析,如何做呢?

查看阿里云官方文档可以知道,我们可以通过阿里云OpenAPI取得专辑和对应的数据表信息,之后将结果落入MaxCompute中

请求专辑信息并且写入到ODPS中

参数:
    1、一组阿里云账号和需要访问的endpoint
    ALIBABA_CLOUD_ACCESS_KEY_ID :key信息
    ALIBABA_CLOUD_ACCESS_KEY_SECRET :secret信息
    ALIBABA_CLOUD_ENDPOINT :阿里云开放API endpoint
    ODPS_ENDPOINT :Maxcompute的endpoint
    
    2、一个ODPS表,用于存储album信息
    TABLE_PROJECT :MAXCOMPUTE的空间名称
    TABLE_NAME :MAXCOMPUTE的表名称
    创建好的table 包含列为:
      {  album_id	string  
        ,album_name	string   专辑名称
        ,entity_type	string 类型
        ,entity_name	string 表名称
        ,project_name	string 项目名称
        ,add_album_time	string 数据表添加到转机时间
        }
    
    3、安装好相关的包
    

STEPS:
    1、读取阿里云开放API的album信息
    2、读取album下的存放在DataFrame对象信息
    3、将数据入到ODPS中
