URL: https://github.com/apache/arrow/issues/35423

   ### Describe the bug, including details regarding any error messages, 
version, and platform.
   
   Arrow 12.0.0 has a regression where it can crash when reading byte-stream 
split encoded data written by itself or older versions of Arrow:
   
   ```python
   import numpy as np
   import pyarrow as pa
   import pyarrow.parquet as pq
   
   x = pa.array(np.linspace(0.0, 1.0, 1_000_000), type=pa.float32())
   table = pa.Table.from_arrays([x], names=['x'])
   pq.write_table(table, 'data.parquet', use_dictionary=False, 
use_byte_stream_split=True)
   
   table = pq.read_table('data.parquet')
   print(table)
   ```
   This crashes with:
   ```
   Traceback (most recent call last):
     File "/home/.../write_read_data.py", line 9, in <module>
        table = pq.read_table('data.parquet')
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
     File 
"/home/adam/.local/share/virtualenvs/arrow12-nieuEBn0/lib64/python3.11/site-packages/pyarrow/parquet/core.py",
 line 2986, in read_table
        return dataset.read(columns=columns, use_threads=use_threads,
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 line 2614, in read
        table = self._dataset.to_table(
                        ^^^^^^^^^^^^^^^^^^^^^^^
     File "pyarrow/_dataset.pyx", line 546, in pyarrow._dataset.Dataset.to_table
     File "pyarrow/_dataset.pyx", line 3449, in 
pyarrow._dataset.Scanner.to_table
     File "pyarrow/error.pxi", line 144, in 
pyarrow.lib.pyarrow_internal_check_status
     File "pyarrow/error.pxi", line 115, in pyarrow.lib.check_status
   OSError: Data size too large for number of values (padding in byte stream 
split data page?)
   ```
   But the above code works fine with pyarrow 11.0.0 and and 10.0.1.
   
   It appears that #34140 caused this regression. I tested building pyarrow on 
the current main branch (commit 42d42b1194d8a672e13dac10a8102573f787f70d) and 
could reproduce the error, but it was fixed after I reverted the merge of that 
PR (commit c31fb46544b9c8372e799138bad9223162169473).
