    AnalyticDB:TPC-DS performance testing

    Last Updated:May 08, 2025

    Transaction Processing Performance Council - Decision Support (TPC-DS) is a decision support benchmark that evaluates the performance of data warehouses. This topic describes how to use TPC-DS to test the performance of AnalyticDB for PostgreSQL on a test set of 100 GB.

    Prerequisites

    Test environment

    AnalyticDB for PostgreSQL instance specifications

    ECS instance specifications

    • Instance resource type: elastic storage mode

    • Engine version: 7.0 Standard Edition

    • Product type: Standard Edition

    • Edition: High-availability Edition

    • Coordinator node resources: 8 compute units (CUs)

    • Compute node specifications: 2 cores, 16 GB

    • Number of compute nodes: 8

    • Disk type: PL1 Enterprise SSD (ESSD)

    • Minor version: 7.1.1.1

    • Instance type: memory-optimized r7/ecs.r7.large (2 vCPUs, 16 GiB)

    • Image: Alibaba Cloud Linux 3.2104 LTS 64-bit (security hardening)

    • System disk: PL0 ESSD with 40 GiB of storage capacity (maximum IOPS per disk: 10,000)

    • Data disk: ESSD AutoPL1 with 2,300 GiB of storage capacity

    Generate test data

    This section describes how to generate TPC-DS test data by using the toolkit provided by TPC.

    1. Download and decompress tpcds-kit.tar and access the tools directory.

      tar -xvf tpcds-kit.tar
cd tpcds-kit/tools

    2. Save the following script as a .sh file. Run the ./ command to execute this file to generate 100 GB of TPC-DS test data.

      # Parameters: 
# SCALE specifies the size of the tpcds dataset to be generated. Unit: GB.
# PARALLEL specifies the number of files to split the data into. The optimal number of files is an integer multiple of the number of compute nodes.
FOR ((i=1;i<=16;i++));
DO
./dsdgen -TERMINATE N -SCALE 100 -PARALLEL 16 -CHILD $i &
done

wait
      Note

      If the ./dsdgen: cannot execute binary file: Exec format error error occurs, run the following code and repeat Step 2 to generate test data:

      sudo yum install byacc flex # Install yacc and flex.
make clean 
make OS=LINUX

    3. Use ossutil to upload the test data to the OSS bucket. For information about the installation and use of the ossutil tool, see ossutil 1.0.

      ./ossutil64 cp -r <path of test data> <path of OSS bucket> --exclude "*.dat*"

      Example:

      ./ossutil64 cp -r /mnt/dbqgen/ oss://testBucketName --exclude "*.dat*"

    4. Create data tables.

    5. Create OSS foreign tables. OSS foreign tables are used to import test data from OSS.

      • The bucket parameter specifies the OSS bucket in which the test data is stored. The endpoint parameter specifies the endpoint of the OSS bucket. For information about how to obtain the OSS bucket and the endpoint, see Obtain the OSS bucket information.

      • The ID and Key parameters specify the AccessKey ID and the AccessKey secret of your Alibaba Cloud account or RAM user. For information about how to obtain the AccessKey ID and the AccessKey secret, see Create an AccessKey pair.
