This PR and benchmark got me thinking - it is faster to clone an array than to create the equivalent null array from scratch (as can be seen in micro benchmarks above). But we could clone the contents of the array and only create the zeroed null buffer. It can increase memory usage though - as the contents might be big, for string arrays, which could be deallocated otherwise if it has a reference count of 0. -- This is an automated message from the Apache Git Service.
