Session
Polars is a dataframe library which has taken the world by storm over the last 4-5 years. Because people love benchmarks, people often compare it with SQL-like engines such as DuckDB, PySpark, Daft, and others. But what if, instead of comparing performance, we compared semantics?
This talk will make no mention whatsoever of performance differences. Instead, it will focus entirely on the semantic differences - which don't get nearly enough attention - of Polars vs SQL. Attendees will leave with a heightened appreciation for the differences between the Polars and SQL models, and an understanding of the consequences this has on their code.
