westonpace opened a new issue, #15130: URL: https://github.com/apache/arrow/issues/15130
### Describe the enhancement requested We've slowly been migrating to a model where all work done by the exec plan happens via the scheduler. We are at a point now where it is mostly true that "a plan is done when all of its tasks are done". We can get rid of `ExecNode::finished()` which has led to a few deadlocks in the exec plan because nodes would fail to mark this future finished in an error case. Any work that is not being tracked by scheduler tasks (e.g. some stuff in the source node and asof join node) should be handled by an "external task". ### Component(s) C++ -- This is an automated message from the Apache Git Service.
