Polars is an open-source DataFrame library for data manipulation and analysis. It is implemented in Rust and uses Apache Arrow’s columnar memory format for efficient data processing.
One of the most well-known facts about Polars is that it is written inRust, a low-level language that is almost as fast as C and C++. In contrast, pandas is built on top of Python libraries, one of these beingNumPy. While NumPy’s core is written in C, it is still hamstrung by ...
