[jira] [Created] (ARROW-8732) [C++] Let Futures support cancellation

Antoine Pitrou created ARROW-8732:
-------------------------------------

             Summary: [C++] Let Futures support cancellation
                 Key: ARROW-8732
                 URL: https://issues.apache.org/jira/browse/ARROW-8732
             Project: Apache Arrow
          Issue Type: Wish
          Components: C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou


There should be a way for consumers of Futures to notify that they are not interested in the task at hand anymore. For some kinds of tasks this may allow cancelling the task in-flight (e.g. an IO task, or a task consisting of multiple steps).
