> Per August 2016 mailing list question re: big endian platforms, we have in the format
document:
> https://github.com/apache/arrow/blob/master/format/Layout.md#byte-order-endianness
> We should clarify that this does not mean that Arrow cannot be used on big endian platforms,
but rather that the canonical or "in-flight" memory representation (for IPC or memory sharing
of any kind) is little-endian, so big endian systems would need to byte swap big endian integers
if they intend to expose memory to any other system using Arrow.
