[jira] [Commented] (ARROW-8301) [C++][Python][R] Handle ChunkedArray and Table in C data interface

    [ https://issues.apache.org/jira/browse/ARROW-8301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17144890#comment-17144890 ] 

Antoine Pitrou commented on ARROW-8301:
---------------------------------------

Could you elaborate on the use case? Is it suboptimal, for example, to export your Table one batch at a time?

Also cc [~wesm] for advice.
