TPC-H Benchmark

TPC-H — это benchmark для систем поддержки принятия решений, разработанный Transaction Processing Performance Council (TPC). Он состоит из набора бизнес-ориентированных ad-hoc запросов и параллельных модификаций данных. TPC-H может использоваться для построения моделей на основе реальных production-сред для симуляции хранилища данных системы продаж. Этот тест использует восемь таблиц с размером данных от 1 ГБ до 3 ТБ. Тестируется всего 22 запроса, основной метрикой производительности является время ответа каждого запроса, то есть длительность между моментом отправки запроса и моментом возврата результата.

1. Выводы тестирования

Сравнительный тест был проведен на наборе данных TPC-H масштаба 100G с общим количеством 22 запросов. Результаты следующие:

Selena тестировала два метода: использование локального хранилища и запросы к таблицам Hive. Таблица Hive в Selena и Trino запрашивают одни и те же данные. Данные хранятся в формате ORC и сжаты в формате zlib.

Задержка для Selena при запросе данных из собственного хранилища составляет 21 с, для Selena при запросе внешних таблиц Hive — 92 с, а для Trino при запросе внешних таблиц Hive — 187 с.

примечание

Единица измерения результатов запросов — мс. Чем меньше, тем лучше. Все запросы прогреваются 1 раз, затем выполняются 3 раза, и берется среднее значение в качестве результата.

4. Процесс тестирования

4.1 Запрос к нативной таблице Selena

4.1.1 Генерация данных

Скачайте пакет инструментов tpch-poc для генерации данных для стандартного набора тестов TPC-H scale factor=100.

wget https://selena-public.oss-cn-zhangjiakou.aliyuncs.com/tpch-poc-1.0.zip
unzip tpch-poc-1.0
cd tpch-poc-1.0

sh bin/gen_data/gen-tpch.sh 100 data_100

4.1.2 Создание структуры таблиц

Измените конфигурационный файл conf/selena.conf, укажите адрес cluster (хост и порт), затем выполните операцию создания таблиц.

sh bin/create_db_table.sh ddl_100

4.1.3 Импорт данных

sh bin/stream_load.sh data_100

4.1.4 Запрос данных

sh bin/benchmark.sh

4.2 Запрос к внешним таблицам Hive с помощью Selena

4.2.1 Создание структуры таблиц

Создайте внешнюю таблицу в Hive. Формат хранения внешней таблицы — ORC, формат сжатия — zlib. Для подробных инструкций по созданию таблиц см. 5.3. Эта внешняя таблица Hive используется как для запросов Selena, так и для запросов Trino.

http://localhost:3000/docs/benchmarking/TPC-H_Benchmarking/

4.2.2 Импорт данных

Загрузите исходные данные TPC-H в формате CSV, сгенерированные на шаге 4.1.1, в указанный путь HDFS (в этой статье используется путь /user/tmp/csv/), затем создайте внешнюю таблицу в Hive. Для подробных инструкций по созданию таблиц см. 5.4. Формат хранения этой внешней таблицы Hive — CSV, путь хранения — /user/tmp/csv/, путь, куда загружены исходные данные CSV.

Импортируйте данные из внешней таблицы в формате CSV во внешнюю таблицу в формате ORC с помощью INSERT INTO, чтобы данные были получены в формате хранения ORC и формате сжатия zlib. Команда импорта следующая:

use tpch_hive_csv;

insert into tpch_hive_orc.customer select * from customer;
insert into tpch_hive_orc.lineitem select * from lineitem;
insert into tpch_hive_orc.nation select * from nation;
insert into tpch_hive_orc.orders select * from orders;
insert into tpch_hive_orc.part select * from part;
insert into tpch_hive_orc.partsupp select * from partsupp;
insert into tpch_hive_orc.region select * from region;
insert into tpch_hive_orc.supplier select * from supplier;

4.2.3 Запрос данных

Selena использует функцию Catalog для запроса данных таблиц Hive. Для подробных операций см. Hive catalog.
