asfimport opened a new issue, #25822:
URL: https://github.com/apache/arrow/issues/25822
Take() currently concatenates ChunkedArrays first. However, this breaks down
when calling Take() from a ChunkedArray or Table where concatenating the arrays
would result in an array that's too large. While inconvenient to implement, it
would be useful if this case were handled.
This could be done as a higher-level wrapper around Take(), perhaps.
Example in Python:
```python
>>> import pyarrow as pa
>>> pa.__version__
'1.0.0'
>>> rb1 = pa.RecordBatch.from_arrays([["a" * 2**30]], names=["a"])
>>> rb2 = pa.RecordBatch.from_arrays([["b" * 2**30]], names=["a"])
>>> table = pa.Table.from_batches([rb1, rb2], schema=rb1.schema)
>>> table.take([1, 0])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pyarrow/table.pxi", line 1145, in pyarrow.lib.Table.take
File
"/home/lidavidm/Code/twosigma/arrow/venv/lib/python3.8/site-packages/pyarrow/compute.py",
line 268, in take
return call_function('take', [data, indices], options)
File "pyarrow/_compute.pyx", line 298, in pyarrow._compute.call_function

pyarrow.lib.pyarrow_internal_check_status
File "pyarrow/error.pxi", line 84, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: offset overflow while concatenating arrays
```
In this example, it would be useful if Take() or a higher-level wrapper
could generate multiple record batches as output.
