Wes McKinney commented on ARROW-3126:
-------------------------------------
{{open_stream}} only uses InputStream
https://github.com/apache/arrow/blob/master/python/pyarrow/ipc.pxi#L247. So we

> [Python] Add buffering option to pyarrow.open_stream to enable larger read
> ahead window for high latency file systems
