AnalyticDB:TPC-H performance testing for AnalyticDB for PostgreSQL V6.0

About TPC-H

The following description is quoted from the TPC Benchmark™ H (TPC-H) specification:

TPC-H is a decision support benchmark. It consists of a suite of business-oriented ad hoc queries and concurrent data modifications. The queries and the data populating the database have been chosen to have broad industry-wide relevance. This benchmark illustrates decision support systems that examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions.

For more information, see TPC Benchmark™ H Standard Specification.

Prerequisites

• An Alibaba Cloud account is created.

• An AnalyticDB for PostgreSQL instance is created. For more information, see Create an instance.

  In this topic, the AnalyticDB for PostgreSQL instance used for testing has the following specifications:

  • Engine version: 6.0 Standard Edition

  • Compute node specifications: 2 cores, 16 GB

  • Number of compute nodes: 32

  • Disk type: enhanced SSD (ESSD)

  • Storage capacity per compute node: 200 GB

• An Elastic Compute Service (ECS) instance is created. For more information, see Creation methods.

  In this topic, the ECS instance used for testing has the following specifications:

  • Instance type: ecs.g6e.4xlarge

  • Operating system: CentOS 7.x

  • System disk: PL1 ESSD with 40 GiB of storage capacity

  • Data disk: PL3 ESSD with 2,048 GiB of storage capacity

    Note

    The ECS instance must be attached with a database. For more information, see Initialize a data disk whose size does not exceed 2 TiB on a Linux instance.

• Object Storage Service (OSS) is activated, and an OSS bucket is created. For more information, see Create buckets.

• The IP address of the ECS instance is added to a whitelist of the AnalyticDB for PostgreSQL instance. For more information, see Configure an IP address whitelist.

• psql is installed on the ECS instance. For more information, see the "psql" section of the Use client tools to connect to an instance topic.

Generate test data

1. Log on to the ECS instance. For more information, see Connect to an instance.

2. Run the following commands on the ECS instance to download the TPC-H DBGEN code to the data disk and compile the code.

   In this example, the directory of the data disk is /mnt.

   wget https://github.com/electrum/tpch-dbgen/archive/refs/heads/master.zip
   yum install -y unzip zip
   unzip master.zip
   cd tpch-dbgen-master/
   echo "#define EOL_HANDLING 1" >> config.h # Delete the vertical bars (|) at the end of each row of data.
   make
   ./dbgen --help

3. Run the following command on the ECS instance to generate a test dataset of 1 TB. We recommend that you split the dataset into multiple data files, and the number of files equals the number of compute nodes in the AnalyticDB for PostgreSQL instance. For example, 32 data files are created by the following sample code, because the AnalyticDB for PostgreSQL instance in this example has 32 compute nodes.

   for((i=1;i<=32;i++));
   do
       ./dbgen -s 1000 -S $i -C 32 -f &
   done 

   Note

   • The volume of data affects the query speed. In TPC-H, scale factors (SFs) are used to describe the data volume. One SF is equal to 1 GB, and 1,000 SFs are equal to 1 TB. One SF contains the data volume of eight tables, excluding the storage occupied by indexes. You must reserve more than one SF of data storage.

   • The dataset may take a long time to be generated. You can run the ps -fHU $USER | grep dbgen command to check whether the generation process is complete.

Create a test table

1. Use psql to connect to the AnalyticDB for PostgreSQL instance. For more information, see the "psql" section of the Use client tools to connect to an instance topic.

2. Execute the following statements to create eight tables for testing:

   CREATE TABLE NATION (
       N_NATIONKEY  INTEGER NOT NULL,

Import data

This section describes how to import data into a database of the AnalyticDB for PostgreSQL instance.

1. Execute the following statements to import the nation and region tables into the database:

   \copy nation from '/mnt/tpch-dbgen-master/nation.tbl' DELIMITER '|';
   \copy region from '/mnt/tpch-dbgen-master/region.tbl' DELIMITER '|';

   Note

   You must replace /mnt/tpch-dbgen-master in the sample statements with the actual directories of nation.tbl and region.tbl.

2. Upload the other six tables to the OSS bucket by using ossutil. For more information about how to use ossutil, see Overview.

   Note

   You cannot write large amounts of data in parallel because the COPY statement writes data in series by using the coordinator node. Therefore, the OSS bucket is required to import data.

   1. Run the following command to download ossutil on the ECS instance:

      wget http://gosspublic.alicdn.com/ossutil/1.7.3/ossutil64

   2. Run the following command to grant the execute permissions on the files:

      chmod 755 ossutil64

   3. Execute the following statements to upload the .tbl files of the six tables to the OSS bucket by using ossutil:

      ls <table_name>.tbl* | while read line;
      do
      ~/ossutil64 -e <EndPoint> -i <AccessKey ID> -k <Access Key Secret> cp $line oss://<OSS Bucket>/<Directory>/ &
      done

3. After all tables are uploaded to the OSS bucket, execute the following statements to import the tables from the bucket to the AnalyticDB for PostgreSQL database. For more information, see Use the COPY or UNLOAD statement to import or export data between OSS foreign tables and AnalyticDB for PostgreSQL tables.

   COPY customer
   FROM 'oss://<OSS Bucket>/<Directory>/customer.tbl'
   ACCESS_KEY_ID '<AccessKey ID>'
   SECRET_ACCESS_KEY '<Access Key Secret>'
   FORMAT AS text
   "delimiter" '|'
   "null" ''
   ENDPOINT '<EndPoint>'
   FDW 'oss_fdw'
   ;
   
   COPY lineitem
   FROM 'oss://<OSS Bucket>/<Directory>/lineitem.tbl'
   ACCESS_KEY_ID '<AccessKey ID>'
   SECRET_ACCESS_KEY '<Access Key Secret>'
   FORMAT AS text
   "delimiter" '|'
   "null" ''
   ENDPOINT '<EndPoint>'
   FDW 'oss_fdw'
   ;
   
   -- The lineitem table defines the sort key column based on which you can sort the data after the import is complete.
   sort lineitem;
   
   COPY orders
   FROM 'oss://<OSS Bucket>/<Directory>/orders.tbl'
   ACCESS_KEY_ID '<AccessKey ID>'
   SECRET_ACCESS_KEY '<Access Key Secret>'
   FORMAT AS text
   "delimiter" '|'
   "null" ''
   ENDPOINT '<EndPoint>'
   FDW 'oss_fdw'
   ;
   
   -- The orders table defines the sort key column based on which you can sort the data after the import is complete.
   sort orders;
   
   COPY part
   FROM 'oss://<OSS Bucket>/<Directory>/part.tbl'
   ACCESS_KEY_ID '<AccessKey ID>'
   SECRET_ACCESS_KEY '<Access Key Secret>'
   FORMAT AS text
   "delimiter" '|'
   "null" ''
   ENDPOINT '<EndPoint>'
   FDW 'oss_fdw'
   ;
   
   COPY supplier
   FROM 'oss://<OSS Bucket>/<Directory>/supplier.tbl'
   ACCESS_KEY_ID '<AccessKey ID>'
   SECRET_ACCESS_KEY '<Access Key Secret>'
   FORMAT AS text
   "delimiter" '|'
   "null" ''
   ENDPOINT '<EndPoint>'
   FDW 'oss_fdw'
   ;
   
   COPY partsupp
   FROM 'oss://<OSS Bucket>/<Directory>/partsupp.tbl'
   ACCESS_KEY_ID '<AccessKey ID>'
   SECRET_ACCESS_KEY '<Access Key Secret>'
   FORMAT AS text
   "delimiter" '|'
   ENDPOINT '<EndPoint>'
   FDW 'oss_fdw'
   ;

Execute queries

You can run a Shell script to start the test or use a client tool such as psql to execute SQL queries one by one. This section describes the two methods.
