Currently, our Parquet writing code writes tables to files on a 1:1 basis, with no built-in support for automatic hierarchical layouts or metadata files.
We should offer Spark/Dask-style support for this:

We should also add support for partitioned writing similar to pyarrow.parquet.write_to_dataset.
