Wes McKinney commented on ARROW-3767:
-------------------------------------
Some memory buffers will have to be allocated to conform to the columnar format
(for primitive types, string, lists, etc.) but that shouldn't be too bad to
build. We should try to use as much common utility code for this as possible
> [C++] Add cast for Null to any type
