一、数仓开发之ODS层
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)
1.1 日志表
1、建表数据
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,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,source_type: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,`order`:STRING,pos_id:STRING>> COMMENT '曝光信息',
`start`
STRUCT<entry:STRING,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> COMMNET '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/';
2、数据装载
load data inpath '/orgin_data/gmall/log/topic_log/2020-06-14' into table ods_log_inc partition by(dt='2020-06-14');
3、每日数据装载脚本
(1)在hadoop102的/home/zhm/bin目录下创建hdfs_to_ods_log.sh
vim hdfs_to_ods_log.sh
(2)添加如下内容
#!/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)增加脚本权限
chmod +x hdfs_to_ods_log.sh
(4)脚本用法
hdfs_to_ods_log.sh 2020-06-14
