Jeroen Janssens and I joined Joe Reis to talk about all things Polars: where it came from, why it is worth switching to, and how we approached writing the book.

Topics covered:

  • Evolution of Polars: From a side project at Xomnia to a widely adopted DataFrame library.
  • Why switch from Pandas: The performance and ergonomics case for Polars in real data pipelines.
  • Writing the book: How Jeroen and I structured the content and what was hardest to explain.
  • Real-world adoption: What we have seen from teams migrating large codebases.
