[jira] [Created] (ARROW-16260) [C++] Add backpressure to aggregate node

Weston Pace created ARROW-16260:
-----------------------------------

             Summary: [C++] Add backpressure to aggregate node
                 Key: ARROW-16260
                 URL: https://issues.apache.org/jira/browse/ARROW-16260
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace


There are two possible cases I can think of where we might need backpressure handling in aggregate node, though both are not a concern until we have spillover

* Once we have spillover we may want to pause the input while we are busy spilling to disk
* Once we have spillover we may want to pause reading from the spillover cache if the sink is busy
