Jeroen Janssens and Thijs Nieuwdo join me to chat about all things Polars. We discuss the evolution of the Polars library, its advantages over pandas, and their journey of writing 'Python Polars: The Definitive Guide.'

Delta Lake has proven to be an excellent storage format. Coupled with the Databricks platform, the storage format has shined as a component of a distributed system on the lakehouse. The pairing of Delta and Spark provides an excellent platform, but users often struggle to perform comparable work outside of the Spark ecosystem. Tools such as delta-rs, Polars and DuckDb have brought access to users outside of Spark, but they are only building blocks of a larger system. In this 40-minute talk we will demonstrate how users can use data products on the Nextdata OS data mesh to interact with the Databricks platform to drive Delta Lake workflows. Additionally, we will show how users can build autonomous data products that interact with their Delta tables both inside and outside of the lakehouse platform. Attendees will learn how to integrate the Nextdata OS data mesh with the Databricks platform as both an external and integral component.

Suppose you want to write a data science tool to do feature engineering. Your experience may go like this: - Expectation: you can focus on state-of-the art techniques for feature engineering. - Reality: you keep having to make you codebase more complex because a new dataframe library has come out and users are demanding support for it.

Or rather, it might have gone like that in the pre-Narwhals era. Because now, you can focus on solving the problems which your tool set out to do, and let Narwhals handle the subtle differences between different kinds of dataframe inputs!

Football analytics has rapidly evolved over the past five years, becoming a crucial part of professional and fan discourse. While much of the cutting-edge research remains hidden behind the fences of club training grounds, a growing ecosystem of open-source tools now enables anyone to develop advanced football analytics models.

In this talk, I'll showcase key open-source libraries—Polars for high-performance data processing, Keras for deep learning, and Spektral for Graph Neural Networks (GNNs)—to analyze millions of player coordinates from publicly available high-frequency positional tracking data. I'll demonstrate how these tools can be used to build in-game prediction models and extract advanced football metrics that only the most advanced football clubs currently use.

In this talk, we will report on our experiences switching from Pandas to Polars in a real-world ML project. Polars is a new high-performance dataframe library for Python based on Apache Arrow and written in Rust. We will compare the performance of polars with the popular pandas library, and show how polars can provide significant speed improvements for data manipulation and analysis tasks. We will also discuss the unique features of polars, such as its ability to handle large datasets that do not fit into memory, and how it feels in practice to make the switch from Pandas. This talk is aimed at data scientists, analysts, and anyone interested in fast and efficient data processing in Python.

Pandas is the de-facto standard for data manipulation in python, which I personally love for its flexible syntax and interoperability. But Pandas has well-known drawbacks such as memory in-efficiency, inconsistent missing data handling and lacking multicore-support. Multiple open-source projects aim to solve those issues, the most interesting is Polars.

Polars uses Rust and Apache Arrow to win in all kinds of performance-benchmarks and evolves fast. But is it already stable enough to migrate an existing Pandas' codebase? And does it meet the high-expectations on query language flexibility of long-time Pandas-lovers?

In this talk, I will explain, how Polars can be that fast, and present my insights on where Polars shines and in which scenarios I stay with pandas (at least for now!)

This talk will introduce Polars a blazingly fast DataFrame library written in Rust on top of Apache Arrow. Its a DataFrame library that brings exploratory data analysis closer to the lessons learned in database research.

CPU's today's come with many cores and with their superscalar designs and SIMD registers allow for even more parallelism. Polars is written from the ground up to fully utilize the CPU's of this generation.

Besides blazingly fast algorithms, cache efficient memory layout and multi-threading, it consist of a lazy query engine, allowing Polars to do several optimizations that may improve query time and memory usage.
