    ApsaraDB for ClickHouse：效能測試指南

    更新時間：Jun 30, 2024

    本文以On Time和Star Schema資料集為例，介紹如何將測試資料集匯入雲資料庫ClickHouse並完成效能測試。

    準備工作

    • 已建立雲資料庫ClickHouse叢集。如何建立，請參見建立叢集。

    • 已建立資料庫帳號。如何建立，請參見建立帳號。

    • 已準備一台Linux系統的機器，並將Linux機器的IP地址添加到雲資料庫ClickHouse叢集的白名單中。如何添加，請參見設定白名單。

    • 已安裝與雲資料庫ClickHouse叢集版本對應的clickhouse-client工具。下載連結，請參見clickhouse-client。

    測試說明

    本測試中的所有clickhouse-client命令均在clickhouse-client用戶端的安裝目錄下執行。

    本測試中使用的On Time和Star Schema資料集均引用自ClickHouse開源網站。更多資訊，請參見樣本資料集。

    On Time資料集測試

    1.串連叢集

    在Linux環境中使用clickhouse-client工具串連雲資料庫ClickHouse叢集。

    ./clickhouse-client --host=<資料庫連接地址> --port=<TCP連接埠號碼> --user=<資料庫帳號> --password=<資料庫帳號的密碼>

    2. 建表

    請根據云資料庫ClickHouse叢集的規格下載正確的建表語句指令碼並執行。

    3.下載On Time資料

    說明

    On Time資料集覆蓋的時間區間非常大，下載資料時間較長，同時資料下載過程中會遇到一部分資料已丟失的錯誤。

    echo https://transtats.bts.gov/PREZIP/On_Time_Reporting_Carrier_On_Time_Performance_1987_present_{1987..2021}_{1..12}.zip | xargs -P10 wget --no-check-certificate --continue

    4. 匯入資料至雲資料庫ClickHouse

    請根據如下Shell命令，正確配置ck_url、ck_user、ck_pass和ck_port環境變數，再進行資料匯入。

    export ck_url=<資料庫連接地址>
export ck_user=<資料庫帳號> 
export ck_pass=<資料庫帳號的密碼>
export ck_port=<TCP連接埠號碼> 
for i in *.zip; do echo $i; unzip -cq $i '*.csv' | sed 's/\.00//g' | ./clickhouse-client -h $ck_url -u $ck_user --password $ck_pass --port $ck_port --query="INSERT INTO ontime FORMAT CSVWithNames"; done

    Star Schema資料集測試

    1.串連叢集

    在Linux環境中使用clickhouse-client工具串連雲資料庫ClickHouse叢集。

    ./clickhouse-client --host=<資料庫連接地址> --port=<TCP連接埠號碼> --user=<資料庫帳號> --password=<資料庫帳號的密碼>

    2. 建表

    請根據云資料庫ClickHouse叢集的規格下載正確的建表語句指令碼並執行。

    3. 產生資料檔案

    請根據如下Shell命令，首先複製資料產生專案ssb-dbgen，然後通過make編譯，用命令產生資料檔案customer.tbl、lineorder.tbl、part.tbl和supplier.tbl。

    說明

    樣本中-s 100參數會產生大概6億行的資料（67 GB），您可以根據情況適當調整測試資料量。

    git clone https://github.com/vadimtk/ssb-dbgen.git
cd ssb-dbgen
make
./dbgen -s 100 -T c
./dbgen -s 100 -T l
./dbgen -s 100 -T p
./dbgen -s 100 -T s

    4. 匯入資料至雲資料庫ClickHouse

    請根據如下Shell命令，正確配置ck_url、ck_user、ck_pass和ck_port環境變數，再進行資料匯入。

    export ck_url=<資料庫連接地址>
export ck_user=<資料庫帳號>
export ck_pass=<資料庫帳號的密碼>
export ck_port=<TCP連接埠號碼> 
./clickhouse-client -h <資料庫連接地址> -u <資料庫帳號> --password <資料庫帳號的密碼> --port <TCP連接埠號碼> --query "INSERT INTO customer FORMAT CSV" < ssb-dbgen/customer.tbl
./clickhouse-client -h <資料庫連接地址> -u <資料庫帳號> --password <資料庫帳號的密碼> --port <TCP連接埠號碼> --query "INSERT INTO part FORMAT CSV" < ssb-dbgen/part.tbl
./clickhouse-client -h <資料庫連接地址> -u <資料庫帳號> --password <資料庫帳號的密碼> --port <TCP連接埠號碼> --query "INSERT INTO supplier FORMAT CSV" < ssb-dbgen/supplier.tbl
./clickhouse-client -h <資料庫連接地址> -u <資料庫帳號> --password <資料庫帳號的密碼> --port <TCP連接埠號碼> --query "INSERT INTO lineorder FORMAT CSV" < ssb-dbgen/lineorder.tbl
