[jira] [Created] (ARROW-12938) [C++] Investigate spawning arbitrary callbacks from StopToken

Antoine Pitrou created ARROW-12938:
--------------------------------------

             Summary: [C++] Investigate spawning arbitrary callbacks from StopToken
                 Key: ARROW-12938
                 URL: https://issues.apache.org/jira/browse/ARROW-12938
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou


In some situations, we may want to forward stop requests to external runtimes, e.g. gRPC (see https://github.com/apache/arrow/pull/10318 ), without polling.

Ideally, one may temporarily add a callback to a StopToken. This bears complications, especially in the case where the stop request comes from a signal handler.
