Polars Essentials
26 November, 2024 – Virtual
Get to know Polars: A modern, extremely performant data-processing library. Written in Rust, Polars is extremely fast, supports out-of-core data streaming, true multithreading, a vectorized query engine using Apache Arrow, lazy evaluation, and much more. In this training, you will not only learn how to perform typical data manipulations, such as filtering, selections, and aggregations, but also what sets Polars apart from Pandas and Spark.

What will you learn?
After the training, you will be able to:
Use Polars to perform common data wrangling operations (e.g. transformations, filtering, aggregations, joins) in Python.
Use advanced features of the Polars API such as time-series expressions, selectors and folds.
Understand what differentiates Polars from other tools, and how you can leverage its query engine, concurrency, laziness and other optimizations to maximize performance.
Program
- Introduction to using Polars expressions for transformations, selections and filtering.
- Overview of how Polars is implemented and how it compares to other tools like Pandas, Spark or databases.
- Eager vs. lazy APIs and file readers.
- Advanced data wrangling exercises.
- Advanced topics: time series, selectors, folds and SQL interoperability.
This training is for you, if:
You have some experience using Python and want to learn how to process data using Polars.
You are new to data analysis or already use another data manipulation tool like Pandas, Spark or Dask and want to understand how Polars compares against them.
