    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)
