I found this issue while investigating how we might round-trip Xarray datasets (which contain many ndarray) through Arrow. My impression from the recent comments it that Arrow is really not meant for this. However, given the strong growth of Arrow, many people are nevertheless trying to put ndarrays into it. Huggingface datasets, for example, [uses an ExtensionArray](https://github.com/huggingface/datasets/blob/9f2ff14673cac1f1ad56d80221a793f5938b68c7/src/datasets/features/features.py#L585-L641) to store ndarrays in arrow. Would you say that is aligned with best practices? @NightMachinary and others may want to consider using [Zarr](https://zarr.readthedocs.io/en/stable/) as an efficient storage format for nd-arrays. -- This is an automated message from the Apache Git Service.
