alamb opened a new issue #110: URL: https://github.com/apache/arrow-rs/issues/110
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-10274 The arithmetic kernels that don't use SIMD create a `vec` in memory and later copy that data into a Buffer. Maybe we could directly write the arithmetic result to a mutable buffer and prevent this redundant copy? {code:java} let values = (0..left.len()) .map(|i| op(left.value(i), right.value(i))) .collect::<Vec<T::Native>>(); let data = ArrayData::new( T::get_data_type(), left.len(), None, null_bit_buffer, 0, vec![Buffer::from(values.to_byte_slice())], vec![], );{code} -- This is an automated message from the Apache Git Service.
