David Li commented on ARROW-15778:
----------------------------------
Flight doesn't do any endianness detection/negotiation anyways (it expects
producer/consumer to set appropriate options) though we should eventually fix
that.
> [Java] Endianness field not emitted in IPC stream
> -------------------------------------------------
>
> Key: ARROW-15778
> URL: https://issues.apache.org/jira/browse/ARROW-15778
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java
> Reporter: Antoine Pitrou
> Priority: Major
> Fix For: 8.0.0
>
>
> It seems the Java IPC writer implementation does not emit the Endianness
> information at all (making it Little by default). This complicates
> interoperability with the C++ IPC reader, which does read this information
> and acts on it to decide whether it needs to byteswap the incoming data.
