"""FileIO implementation for reading and writing table files that uses pyarrow.fs.

This file contains a FileIO implementation that relies on the filesystem interface provided
by PyArrow. It relies on PyArrow's `from_uri` method that infers the correct filesystem
type to use. Theoretically, this allows the supported storage types to grow naturally
with the pyarrow library.

    Example:
    Input:
    An arrow table with partition key of ['n_legs', 'year'] and with data of
    {'year': [2020, 2022, 2022, 2021, 2022, 2022, 2022, 2019, 2021],

     'animal': ["Flamingo", "Parrot", "Parrot", "Dog", "Horse", "Horse", "Horse","Brittle stars", "Centipede"]}.
    The algorithm:
    Firstly we group the rows into partitions by sorting with sort order [('n_legs', 'descending'), ('year', 'descending')]
    and null_placement of "at_end".
    This gives the same table as raw input.
    Then we sort_indices using reverse order of [('n_legs', 'descending'), ('year', 'descending')]
    and null_placement : "at_start".
    This gives:
    [8, 7, 4, 5, 6, 3, 1, 2, 0]
    Based on this we get partition groups of indices:
    [{'offset': 8, 'length': 1}, {'offset': 7, 'length': 1}, {'offset': 4, 'length': 3}, {'offset': 3, 'length': 1}, {'offset': 1, 'length': 2}, {'offset': 0, 'length': 1}]
