--------------------------------------
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.
