> That seemed a more suitable strategy because converting from `numpy.array` to `BooleanArray` should usually be zero copy and thus have little overhead That's not actually the case, unfortunately: numpy uses bytes for boolean arrays (like int8), while arrow uses bits. Now, whether this additional conversion step (instead of iterating over the numpy array directly) matters and has a noticeable impact, I don't know (you could time it) -- This is an automated message from the Apache Git Service.
