[jira] [Updated] (ARROW-10185) [C++] Add FinishAsync to TaskGroup

     [ https://issues.apache.org/jira/browse/ARROW-10185?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Antoine Pitrou updated ARROW-10185:
-----------------------------------
    Summary: [C++] Add FinishAsync to TaskGroup  (was: Add FinishAsync to TaskGroup)

> [C++] Add FinishAsync to TaskGroup
> ----------------------------------
>
>                 Key: ARROW-10185
>                 URL: https://issues.apache.org/jira/browse/ARROW-10185
>             Project: Apache Arrow
>          Issue Type: Sub-task
>            Reporter: Weston Pace
>            Priority: Major
>
> As an alternative to Finish, FinishAsync will return a future immediately.  This can then be added to a parent task group, allowing for nested task groups.  Since the future is returned immediately, the child task group is not occupying a thread on the thread pool and there is no concern for thread starvation.
