[jira] [Commented] (ARROW-1846) [C++] Implement "any" reduction kernel for boolean data

    [ https://issues.apache.org/jira/browse/ARROW-1846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17203293#comment-17203293 ] 

Wes McKinney commented on ARROW-1846:
-------------------------------------

It is, but it just needs to be able to short-circuit (i.e. if the max/any value in the state is already true, then skip examining the data chunk) for when we have parallel evaluation
