The TPC-DS (Transaction Processing Performance Council – Decision Support) tools are essential for those looking to benchmark and evaluate the performance of database systems. In this guide, we will break down how to set up the TPC-DS tools on both Linux and macOS, generate data, and create queries, all while troubleshooting common issues along the way.

Getting Started with TPC-DS

The official TPC-DS tools can be found at tpc.org. The version we will focus on is based on v2.10.0, which includes significant modifications such as:

• Compatibility with macOS.
• Fixes for various query template bugs.
• Renaming columns for consistency with specifications.

To see all modifications, diff the files in the master branch with the version branch. For example: master vs v2.10.0.

Setup Instructions

For Linux Users

1. Ensure you have the required development tools installed:
2. For Ubuntu, run:

sudo apt-get install gcc make flex bison byacc git

3. For CentOS/RHEL, run:

sudo yum install gcc make flex bison byacc git

4. Clone the repository and build the tools:

git clone https://github.com/gregrahn/tpcds-kit.git

cd tpcds-kit/tools

make OS=LINUX

For macOS Users

1. Ensure you have the required development tools installed:

xcode-select --install

2. Clone the repository and build the tools:

git clone https://github.com/gregrahn/tpcds-kit.git

cd tpcds-kit/tools

make OS=MACOS

Using the TPC-DS Tools

Data Generation

Data generation is accomplished using the dsdgen tool. For a thorough understanding of the available options, run:

dsdgen -help

Note that if you do not run dsdgen from the tools directory, you must use the option -DISTRIBUTIONS ... with the path to your data index file. Also remember that the output directory specified via the -DIR option must exist prior to execution.

Query Generation

Query generation can be done via the dsqgen tool, which is similar to creating a film script based on a template. You provide the tool with a script (template), and it generates numerous variations (queries) based on that template.

The command below can be used to generate all 99 queries numerically ordered with a scale factor of 10TB:

dsqgen -DIRECTORY ../query_templates -INPUT ../query_templates/templates.lst -VERBOSE Y -QUALIFY Y -SCALE 10000 -DIALECT netezza -OUTPUT_DIR tmp

Troubleshooting Tips

Encountering issues during setup or execution? Here are some common troubleshooting ideas:

• Ensure that all necessary packages are installed based on your operating system.
• If you’re having issues with query generation, double-check that your output directory exists and the template paths are correct.
• For specific error messages, refer to the GitHub issues pages linked in the modifications for potential solutions.
