Utilities for running the TPC-H queries via Narwhals.

Here's an (opinionated) guide to how to get setup:

Environment setup:

• install uv
• install Python3.12: uv python install 3.12
• create a virtual environment: uv venv -p 3.12 --seed
• activate it as per instructions shown on the terminal
• install requirements: uv pip install -r requirements.txt

Generate data

Run python generate_data.py.

Run queries

To run Q1, you can run python -m execute.q1.

Please add query definitions in queries, and scripts to execute them in execute (see queries/q1.py and execute/q1.py for examples).
