Project mention: How moving from Pandas to Polars made me write better code without writing better code | dev.to | 2024-03-05

In comes Polars: a brand new dataframe library, or how the author Ritchie Vink describes it... a query engine with a dataframe frontend.

Project mention: A Polars exploration into Kedro | dev.to | 2023-05-17

The interesting thing about Polars is that it does not try to be a drop-in replacement to pandas, like Dask, cuDF, or Modin, and instead has its own expressive API. Despite being a young project, it quickly got popular thanks to its easy installation process and its “lightning fast” performance.
