quick clarifying question if i may: is this library solely concerned with reading? it does not handle numpy type conversion to BSON on DB write?

context: it appears numpy.bool_ fails to BSON-serialize with numpy v2 https://github.com/materialsproject/fireworks/issues/522

pre-commit should be green now.

thanks for the quick reply, good to know about write! is there some function that recursively converts a dict containing numpy/pandas types to std lib Python types?

Yes, you can see it here: https://github.com/mongodb-labs/mongo-arrow/blob/1.3.0/bindings/python/pymongoarrow/api.py#L417
