[jira] [Commented] (ARROW-6123) [C++] ArgSort kernel should not materialize the output internal

    [ https://issues.apache.org/jira/browse/ARROW-6123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17448134#comment-17448134 ] 

Antoine Pitrou commented on ARROW-6123:
---------------------------------------

[~fsaintjacques] probably meant that the output area should be preallocated by the generic kernel machinery instead? But that doesn't sound like a big deal, especially as sorting is a heavy operation.
