> [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
> Priority: Major
>
> 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.
