Wes has also worked hard to improve a lot of the missteps of pandas, such as through pyarrow, which may prove even more impactful than pandas has been to date.

Polars is also a wonderful project!



Polars is also based on McKinney’s Arrow project.

Polars is a DataFrame interface on top of an OLAP Query Engine implemented in Rust using Apache Arrow Columnar Format as the memory model.

Wes also literally created another Python dataframe project, Ibis, to overcome many of the issues with pandas

most data engines and dataframe tools these days use Apache Arrow, it's a bit orthogonal
