ClickHouse提供了Yandex.Metrica的脱敏数据集,用户可以使用这个测试数据集体验ClickHouse的特性。

下载测试数据集

curl https://datasets.clickhouse.tech/hits/tsv/hits_v1.tsv.xz | unxz --threads=`nproc` > hits_v1.tsv

curl https://datasets.clickhouse.tech/visits/tsv/visits_v1.tsv.xz | unxz --threads=`nproc` > visits_v1.tsv

hits_v1.tsv大小为7.3G,visits_v1.tsv大小为2.5G

建库建表

clickhouse-client --query "CREATE DATABASE IF NOT EXISTS tutorial"

如果修改了tcp_port默认的9000端口,需要加上–port参数指定端口。

clickhouse-client --port 9020 --query "CREATE DATABASE IF NOT EXISTS tutorial"

官方给的建表语句很长,建议通过DBeaver工具来建表

hits_v1使用的是MergeTree,visits_v1使用的是CollapsingMergeTree

导入数据

clickhouse-client --query "INSERT INTO tutorial.hits_v1 FORMAT TSV" --max_insert_block_size=100000 < hits_v1.tsv

clickhouse-client --query "INSERT INTO tutorial.visits_v1 FORMAT TSV" --max_insert_block_size=100000 < visits_v1.tsv

ClickHouse会在一段时间后对导入的表进行后台数据存储优化。当然,也可以使用OPTIMIZE TABLE语句对表立即进行数据存储优化。

clickhouse-client --query "OPTIMIZE TABLE tutorial.hits_v1 FINAL"
clickhouse-client --query "OPTIMIZE TABLE tutorial.visits_v1 FINAL"

检查是否导入成功。

clickhouse-client --query "SELECT COUNT(*) FROM tutorial.hits_v1"
clickhouse-client --query "SELECT COUNT(*) FROM tutorial.visits_v1"

ClickHouse导入测试数据集

样例查询

SELECT
    StartURL AS URL,
    AVG(Duration) AS AvgDuration
FROM tutorial.visits_v1
WHERE StartDate BETWEEN '2014-03-23' AND '2014-03-30'
GROUP BY URL
ORDER BY AvgDuration DESC
LIMIT 10

ClickHouse导入测试数据集

SELECT
    sum(Sign) AS visits,
    sumIf(Sign, has(Goals.ID, 1105530)) AS goal_visits,
    (100. * goal_visits) / visits AS goal_percent
FROM tutorial.visits_v1
WHERE (CounterID = 912887) AND (toYYYYMM(StartDate) = 201403) AND (domain(StartURL) = 'yandex.ru')
