Column.arrow

the underlying pyarrow ChunkedArray, zero-copy

Python

arrow: pyarrow.ChunkedArray

Returns pyarrow.ChunkedArray — the underlying array (zero-copy)

Example#

Python

import pyarrow.compute as pc
col = t["score"]
pc.mean(col.arrow).as_py()          # drop into raw Arrow compute

Notes#

arrow is zero-copy — it returns the exact ChunkedArray (or Array) the Column wraps. It is the escape hatch for any Arrow kernel the operator set does not cover; the Table-level equivalent is Table.arrow.
