TPC-H 基准测试

TPC-H 是美国交易处理效能委员会 TPC（Transaction Processing Performance Council）组织制定的用来模拟决策支持类应用的测试集。它包括一整套面向业务的 ad-hoc 查询和并发数据修改。

TPC-H 根据真实的生产运行环境来建模，模拟了一套销售系统的数据仓库。该测试共包含 8 张表，数据量可设定从 1 GB~3 TB不等。其基准测试共包含了 22 个查询，主要评价指标为各个查询的响应时间，即从提交查询到结果返回所需时间。

1. 测试结论

在 TPC-H 100G 规模的数据集上进行对比测试，共 22 个查询，结果如下：

StarRocks 测试了使用本地存储查询和 Hive 外表查询两种方式，其中 StarRocks Hive 外表和 Trino 查询的是同一份数据，数据采用 ORC 格式存储，zlib 格式压缩。

最终，StarRocks 本地存储查询总耗时为 17s，StarRocks Hive 外表查询总耗时为 92s，Trino 查询总耗时为187s。

4. 测试流程

4.1 StarRocks 本地表测试流程

4.1.1 生成数据

下载 tpch-poc 工具包生成 TPC-H 标准测试集 scale factor=100 的数据。

wget https://starrocks-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 创建表结构

修改配置文件 conf/starrocks.conf，指定脚本操作的集群地址，重点关注 mysql_host 和 mysql_port，然后执行建表操作。

sh bin/create_db_table.sh ddl_100

4.1.3 导入数据

sh bin/stream_load.sh data_100

4.1.4 查询数据

sh bin/benchmark.sh

4.2 StarRocks Hive 外表测试流程

4.2.1 创建表结构

在 Hive 中创建外部表，外部表存储格式是 ORC，压缩格式是 zlib，详细建表语句见 5.3，这个 Hive 外部表就是StarRocks 和 Trino 对比测试查询的表。

4.2.2 导入数据

将步骤 4.1.1 中生成的 TPC-H CSV 原始数据上传到 HDFS 指定路径上，本文以路径 /user/tmp/csv/ 举例，然后在 Hive 中创建外部表，详细建表语句见 5.4。这个 Hive 外部表存储格式为 CSV，存储路径为 CSV 原始数据上传的路径 /user/tmp/csv/。

通过 insert into 将 CSV 格式外部表的数据导入到 ORC 格式的外部表中，这样就得到了存储格式为 ORC，压缩格式为 zlib 的数据，导入命令如下：

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 查询数据

StarRocks 使用 Catalog 功能查询 Hive 外表数据，详细操作见 Hive catalog。
