------------------------------------------------------------------

One solution that does not requires any modification to current Arrow/Cython is to first retrieve an `Array` via `column` and then get the `ArrayData` via the `data()` method.

{code:python}
cdef shared_ptr[CRecordBatch] record = pyarrow_unwrap_batch(obj)
array_data = record.get().column(1).data()
{code}
