Description

Slowest test durations:

3.73s call     pyarrow/tests/test_parquet.py::test_set_data_page_size
0.05s call     pyarrow/tests/test_parquet.py::test_nested_list_nonnullable_roundtrip_bug
0.03s call     pyarrow/tests/test_parquet.py::test_compression_level
0.03s call     pyarrow/tests/test_parquet.py::test_dictionary_array_automatically_read
0.02s call     pyarrow/tests/test_parquet.py::test_statistics_convert_logical_types
0.02s call     pyarrow/tests/test_parquet.py::test_large_list_records
0.01s call     pyarrow/tests/test_parquet.py::test_write_nested_zero_length_array_chunk_failure
0.01s call     pyarrow/tests/test_parquet.py::test_parquet_write_disable_statistics
0.01s call     pyarrow/tests/test_parquet.py::test_single_pylist_column_roundtrip[int]
0.01s call     pyarrow/tests/test_parquet.py::test_special_chars_filename

This suggests to me there is something wrong with the feature (possibly doing unnecessary work)
