[jira] [Commented] (ARROW-1089) [C++][Python] Add API to write an Arrow stream into either the stream or file formats on disk

    [ https://issues.apache.org/jira/browse/ARROW-1089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17287352#comment-17287352 ] 

Wes McKinney commented on ARROW-1089:
-------------------------------------

What plumbing would be needed to asynchronously consume a RecordBatchReader and write the results to disk? cc [~westonpace] see also ARROW-1009

> For Arrow streams with unknown size, it would be useful to be able to write the data to disk either as a stream or as the file format (for random access) with minimal overhead; i.e. we would avoid record batch IPC loading and write the raw messages directly to disk
