Right, I was missing a cast or two, here's how I'd express the multiply kernel with pyarrow: ```python import pyarrow as pa from pyarrow import compute as pc unit = "ms" a = pa.array([2], pa.duration(unit)) b = pa.array([3.7], pa.float64()) c = pc.multiply(a.cast(pa.int64()), b) result = pc.round_to_multiple(c, 1).cast(pa.int64()).cast(pa.duration(unit)) ``` Question is - should we have a kernel that does all of this in c++ or not. And if yes, should it be under `multiply` or be called something else. -- This is an automated message from the Apache Git Service.
