-------------------------------------
here's a PR: https://github.com/apache/arrow/pull/113
> [Format] Clarify Arrow's relationship with big endian platforms
> ---------------------------------------------------------------
>
> Key: ARROW-245
> URL: https://issues.apache.org/jira/browse/ARROW-245
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Format
> Reporter: Wes McKinney
>
> 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.
