ODS层的设计要点如下：

（1）ODS层的表结构设计依托于从业务系统同步过来的数据结构。

（2）ODS层要保存全部历史数据，故其压缩格式应选择压缩比较高的，此处选择gzip。

（3）ODS层表名的命名规范为：ods_表名_单分区增量全量标识（inc/full）。

7.1 日志表

1）建表语句

DROP TABLE IF EXISTS ods_log_inc;
CREATE EXTERNAL TABLE ods_log_inc
(
    `common` STRUCT<ar :STRING,
        ba :STRING,
        ch :STRING,
        is_new :STRING,
        md :STRING,
        mid :STRING,
        os :STRING,
        sid :STRING,
        uid :STRING,
        vc :STRING> COMMENT '公共信息',
    `page` STRUCT<during_time :STRING,
        item :STRING,
        item_type :STRING,
        last_page_id :STRING,
        page_id :STRING,
        from_pos_id :STRING,
        from_pos_seq :STRING,
        refer_id :STRING> COMMENT '页面信息',
    `actions` ARRAY<STRUCT<action_id:STRING,
        item:STRING,
        item_type:STRING,
        ts:BIGINT>> COMMENT '动作信息',
    `displays` ARRAY<STRUCT<display_type :STRING,
        item :STRING,
        item_type :STRING,
        `pos_seq` :STRING,
        pos_id :STRING>> COMMENT '曝光信息',
    `start` STRUCT<entry :STRING,
        first_open :BIGINT,
        loading_time :BIGINT,
        open_ad_id :BIGINT,
        open_ad_ms :BIGINT,
        open_ad_skip_ms :BIGINT> COMMENT '启动信息',
    `err` STRUCT<error_code:BIGINT,
            msg:STRING> COMMENT '错误信息',
    `ts` BIGINT  COMMENT '时间戳'
) COMMENT '活动信息表'
    PARTITIONED BY (`dt` STRING)
    ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.JsonSerDe'
LOCATION '/warehouse/gmall/ods/ods_log_inc/'
TBLPROPERTIES ('compression.codec'='org.apache.hadoop.io.compress.GzipCodec');

2）数据装载

load data inpath '/origin_data/gmall/log/topic_log/2022-06-08' into table ods_log_inc partition(dt='2022-06-08');

3）每日数据装载脚本

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

[atguigu@hadoop102 bin]$ vim hdfs_to_ods_log.sh

（2）编写如下内容

#!/bin/bash
 
# 定义变量方便修改
APP=gmall
 
# 如果是输入的日期按照取输入日期；如果没输入日期取当前时间的前一天
if [ -n "$1" ] ;then
   do_date=$1
else
   do_date=`date -d "-1 day" +%F`
fi
 
echo ================== 日志日期为 $do_date ==================
sql="
load data inpath '/origin_data/$APP/log/topic_log/$do_date' into table ${APP}.ods_log_inc partition(dt='$do_date');
"
hive -e "$sql"

（3）增加脚本执行权限

[atguigu@hadoop102 bin]$ chmod +x hdfs_to_ods_log.sh

（4）脚本用法

[atguigu@hadoop102 bin]$ hdfs_to_ods_log.sh 2022-06-08
