Lazy mode and query optimisation are key reasons why Polars is such a powerful data analysis tool. In this video I introduce these concepts and how Polars uses them. In the course we look at how lazy mode works with everything from filtering operations, groupby aggregations and joins.

The notebook for this video can be found in this repository along with instructions on how to run it: https://github.com/braaannigan/data-a...
