             Summary: [C++] Add pause capability to async task scheduler and support pause producing in new scan node
                 Key: ARROW-17755
                 URL: https://issues.apache.org/jira/browse/ARROW-17755
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: C++
            Reporter: Weston Pace


When the scanner is asked to pause producing we should be able to simply pause the async task scheduler.  However, the task scheduler does not have a pause capability at the moment.

When the async task scheduler is asked to pause it should simply stop submitting new tasks.  There is no need to worry about the tasks in progress.
