TPC-H Benchmark

概述

TPC-H是一个决策支持基准（Decision Support Benchmark），它由一套面向业务的特别查询和并发数据修改组成，使用的数据具有广泛的行业相关性。该基准测试通过一系列的查询操作来评估数据库系统在处理复杂查询和数据挖掘任务时的性能。TPC-H报告的性能指标称为TPC-H每小时复合查询性能指标(QphH@Size)，该指标反映了系统处理查询能力的多个方面。这些方面包括执行查询时所选择的数据库大小，由单个流提交查询时的查询处理能力，以及由多个并发用户提交查询时的查询吞吐量等。​

测试数据集

整个测试模拟生成TPC-H 100GB和500GB的数据并导入SelectDB进行测试，下面是测试100GB数据表的相关说明及数据量。

测试步骤

以下为测试的详细步骤。如何获取测试中涉及的脚本，请下载瑶池测试工具。

步骤一：安装unzip工具

1. 安装unzip。

   sudo apt install unzip

2. 安装完成后，可以通过运行以下命令来验证unzip是否已成功安装。

   unzip --help

步骤二：下载安装TPC-H数据生成工具

从上述脚本库中获取脚本后，解压脚本文件并进入对应目录，执行以下指令，下载并编译tpch-dbgen工具，示例如下。

tar -zxvf yaochi_performance_tool.tar.gz
cd ./yaochi_performance_tool/tpch-tools/bin
bash build-tpch-dbgen.sh

安装成功后，将在TPC-H_Tools_v3.0.0/目录下生成dbgen二进制文件。

步骤三：生成TPC-H测试集

在安装测试工具目录执行以下脚本生成TPC-H数据集，示例如下。

cd ./yaochi_performance_tool/tpch-tools/bin
bash gen-tpch-data.sh

数据会以.tbl为后缀在tpch-data/目录下生成，默认情况下的文件总大小约100GB。生成时间可能在数分钟到1小时不等。

步骤四：建表

1. 准备doris-cluster.conf文件。

   在调用导入脚本前，需要将测试数据库的连接信息写在doris-cluster.conf文件中。文件位置在tpch-tools/conf/目录下，内容包括连接集群的地址、HTTP端口、用户名、密码和待导入数据的DB。

   说明

   您可以在云数据库 SelectDB 版控制台的实例详情>网络信息中获取VPC地址（或公网地址）和HTTP协议端口。

   export FE_HOST="xxx"
   export FE_HTTP_PORT="8080"
   export FE_QUERY_PORT="9030"
   export USER="root"
   export PASSWORD='xxx'
   export DB="tpch1"

2. 创建TPC-H表。

   在./yaochi_performance_tool/tpch-tools/bin目录下执行脚本来自动创建测试用表。

   bash create-tpch-tables.sh

步骤五：导入数据

在./yaochi_performance_tool/tpch-tools/bin目录下执行脚本完成测试集数据导入。

bash ./load-tpch-data.sh

步骤六：检查导入数据

按照上述流程和参数执行的场合，数据量应和上文测试数据集给出的生成数据的行数一致。

SELECT  COUNT(*) FROM lineitem;
SELECT  COUNT(*) FROM orders;
SELECT  COUNT(*) FROM partsupp;
SELECT  COUNT(*) FROM part;
SELECT  COUNT(*) FROM customer;
SELECT  COUNT(*) FROM supplier;
SELECT  COUNT(*) FROM nation;
SELECT  COUNT(*) FROM region;
SELECT  COUNT(*) FROM revenue0;

步骤七：查询测试

• 执行查询脚本

  执行下面的命令完成查询测试。

  ./run-tpch-queries.sh

  测试SQL详情请参见TPCH-Query-SQL。

  说明

  目前SelectDB的查询优化器和统计信息功能仍有提升空间，所以我们在TPC-H中重写了一些查询以适应SelectDB的执行框架，但不影响结果的正确性。

• 单个 SQL 执行

  下面是本次测试时使用的SQL语句，您也可以从代码库中获取最新的查询语句，最新测试查询语句请参见TPC-H 测试查询语句。
