the panic came from this line which passes a scalar of type StringArray to a comparison kernel with StringViewArray -- the fix was to make the appropriate scalar type with let string_view_scalar = StringViewArray::new_scalar("xxxx");

b.iter(|| eq(&string_view_scalar, &string_view_left).unwrap())
});

I also added a second function for more than 12 bytes
