Apache Arrow seems to be gaining a lot of traction in the dataframe space.
We use polars and it would be great to be able to directly create a dataset from arrow format.
Also, pandas 2.0 will have arrow as a backend later this month .

Consider implementation of the sketchboost algorithm for multi output/multiclass setting. The current multiclass approach is highly ineffecient as a separate tree structure is required for each class. This approach significantly improves on training time and model size by allowing a single tree structure to handle many classes.

This is already implemented in the Py-Boost library.
