Apache Arrow in Mojo

This repo is very much a work in progress. The goal is to provide a way to use Apache Arrow in Mojo. This is a very early version and is not yet ready for use.

Dev Setup

If you have all the prerequisites, you should be able to just run

make setup

Prerequisites

• Mojo
• Python 3.11 (recommended via pyenv, but not required)
• uv for python package management. Needed for make setup to work but optional. You can also use pip install -r requirements.txt instead.

If you would like to manually create your python virtual env, use this command

python3 -m venv .venv

The makefile contains some helpful commands:

• make setup - Install python dependencies & setup .venv
• make test - Run tests
• make fmt - Run formatter
• make build - Build the package
• make clean - Clean up build artifacts

However, for make commands to work MODULAR_HOME and PATH must be configured in ~/.zprofile or ~/.bash_profile in addition to ~/.zshrc or ~/.bashrc.

export MODULAR_HOME="$HOME/.modular"

# Pick one of the following, don't use both
# Option A: Nightly Mojo
export PATH="$HOME/.modular/pkg/packages.modular.com_nightly_mojo/bin:$PATH"
# Option B: Stable Mojo
export PATH="$HOME/.modular/pkg/packages.modular.com_mojo/bin:$PATH"
