-----------------------------------
Summary: [C++] Backpressure should resume as a new task, assuming
executor is present
Key: ARROW-17180
URL: https://issues.apache.org/jira/browse/ARROW-17180
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
As brought up on the mailing list:
https://lists.apache.org/thread/hscjqyw7lpt95vlkzoslm6pyhy9x6wso
When we resume producing in the source node, we should run the continuation
(which starts scanning again) as a new task. This will avoid potential stack
overflow (if we pause and start many times) and help make for more
understandable stack traces. The continuation is unlikely to have anything to
do with the task that is calling resume and so there is not as much downside to
a context switch.
