This repo contains the code used for performance evaluation of polars. The benchmarks are TPC-standardised queries and data designed to test the performance of "real" workflows.

From the TPC website:

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.

Generating TPC-H Data

Project setup

# clone this repository
git clone
cd tpch/tpch-dbgen

# build tpch-dbgen


# change directory to the root of the repository
cd ../

This will do the following,

  • Create a new virtual environment with all required dependencies.
  • Generate data for benchmarks.
  • Run the benchmark suite.
