-----------------------------------
Summary: [C++] Add support for the serial executor to expose an
async generator as an iterable
Key: ARROW-16026
URL: https://issues.apache.org/jira/browse/ARROW-16026
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
The SerialExecutor can currently serialize a future-returning task by running
it in an event loop style executor.
This JIRA is to add support for serializing an async-generator task by turning
it into an iterator. Each time the iterator is polled the generator will be
polled and the event loop will run until an item is delivered and the event
loop is exhausted.
