第10章数仓开发之DWS层

设计要点：

（1）DWS层的设计参考指标体系。

（2）DWS层的数据存储格式为ORC列式存储 + snappy压缩。

（3）DWS层表名的命名规范为dws_数据域_统计粒度_业务过程_统计周期（1d/nd/td）

注：1d表示最近1日，nd表示最近n日，td表示历史至今。

10.1 最近1日汇总表

10.3.4 数据装载脚本

1）首日数据装载脚本

（1）在hadoop102的/home/atguigu/bin目录下创建dws_1d_to_dws_td_init.sh

[atguigu@hadoop102 bin]$ vim dws_1d_to_dws_td_init.sh

（2）编写如下内容

#!/bin/bash
