Polars

Polars is a DataFrame library that leverages Rust's performance and Apache Arrow's columnar format. It's significantly faster than pandas for most operations, especially on large datasets, thanks to parallel execution and lazy evaluation.

Installation

# Python
pip install polars

# With all optional dependencies (Excel, SQL, cloud storage)
pip install 'polars[all]'

# Node.js
npm install nodejs-polars
