Antoine Pitrou commented on ARROW-6554:
---------------------------------------
As answered on the async OutputStream issue, I'm not sure this is useful:
writes are typically issued in the background already. Perhaps we would be
hiding the cost of a system call or something, but not the actual I/O.
> [C++] Implement "background write" option for BufferedOutputStream

> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++

> In such cases we would have to allocate a new buffer on subsequent writes
> (while a background write is completing), but it could yield beneficial
> performance improvements for high latency filesystems
