(Pretty) big data wrangling with DuckDB and Polars
With examples in R and Python
Description
This workshop will introduce you to DuckDB and Polars, two data wrangling libraries at the frontier of high-performance computation. (See benchmarks.) In addition to being extremely fast and portable, both DuckDB and Polars provide user-friendly implementations across multiple languages. This makes them very well suited to production and applied research settings, without the overhead of tools like Spark. We will provide a variety of real-life examples in both R and Python, with the aim of getting participants up and running as quickly as possible. We will learn how wrangle datasets extending over several hundred million observations in a matter of seconds or less, using only our laptops. And we will learn how to scale to even larger contexts where the data exceeds our computers’ RAM capacity. Finally, we will also discuss some complementary tools and how these can be integrated for an efficient end-to-end workflow (data I/O -> wrangling -> analysis).
