1、说明

参考官方教程：https://clickhouse.tech/docs/en/getting-started/tutorial/

Yandex.Metrica is a web analytics service, and sample dataset doesn’t cover its full functionality, so there are only two tables to create: YandexMetrica是一个网络分析服务，样本数据集不包括其全部功能，因此只有两个表可以创建:

hits is a table with each action done by all users on all websites covered by the service.
visits is a table that contains pre-built sessions instead of individual actions.
hits 是一个表格，其中包含所有用户在服务所涵盖的所有网站上完成的每个操作。
visits 是一个包含预先构建的会话而不是单个操作的表。

2、从准备好的分区获取表

2.1 下载数据

由于公司内网限制，不能直接下载数据到服务器。

这里采用Windows系统下载数据，然后上传到Linux服务器

https://clickhouse-datasets.s3.yandex.net/hits/partitions/hits_v1.tar https://clickhouse-datasets.s3.yandex.net/visits/partitions/visits_v1.tar

2.2 导入数据

（1）上传至服务器

[root@elastic1 ~]# ll /tpdata/data/
total 4110280
-rw-r--r-- 1 root root 1271623680 Sep 14 13:59 hits_v1.tar
-rw-r--r-- 1 root root  563968000 Sep 14 13:44 visits_v1.tar
[root@elastic1 ~]#

（2）导入数据注意 /var/lib/clickhouse是当前数据目录。如果数据目录修改，则需要解压缩到对应的目录。

[root@elastic1 data]# tar xvf hits_v1.tar -C /var/lib/clickhouse
data/datasets/hits_v1/
data/datasets/hits_v1/format_version.txt
data/datasets/hits_v1/detached/
data/datasets/hits_v1/201403_10_18_2/
...

[root@elastic1 data]# tar xvf visits_v1.tar -C /var/lib/clickhouse
data/datasets/visits_v1/
data/datasets/visits_v1/format_version.txt
data/datasets/visits_v1/20140317_20140323_3_4_1/
...

（3）重启服务

[root@elastic1 data]# systemctl restart clickhouse-server

2.3 简单统计

[root@elastic1 data]# clickhouse-client --password --query "SELECT COUNT(*) FROM datasets.hits_v1"
Password for user (default): 
8873898
[root@elastic1 data]# clickhouse-client --password --query "SELECT COUNT(*) FROM datasets.visits_v1"
Password for user (default): 
1676861
[root@elastic1 data]#

3、从压缩TSV文件获取表

3.1 下载压缩文件

https://clickhouse-datasets.s3.yandex.net/hits/tsv/hits_v1.tsv.xz https://clickhouse-datasets.s3.yandex.net/visits/tsv/visits_v1.tsv.xz

[root@elastic1 data]# ll
total 6478640
drwxr-xr-x 3 root root       4096 Sep 14 15:09 data
-rw-r--r-- 1 root root 1271623680 Sep 14 13:59 hits_v1.tar
-rw-r--r-- 1 root root  841046840 Sep 14 16:37 hits_v1.tsv.xz
drwxr-xr-x 3 root root       4096 Sep 14 15:09 metadata
-rw-r--r-- 1 root root 3532492212 Sep 14 15:38 ontime.csv.xz
-rw-r--r-- 1 root root  563968000 Sep 14 13:44 visits_v1.tar
-rw-r--r-- 1 root root  424963796 Sep 14 16:27 visits_v1.tsv.xz
[root@elastic1 data]#

3.2 新建数据表

（1）新建数据库

[root@elastic1 ~]# clickhouse-client --password --query "CREATE DATABASE IF NOT EXISTS tutorial"
Password for user (default): 
[root@elastic1 ~]#

（2）新建tutorial.hits_v1
