[jira] [Created] (ARROW-8626) [C++] Implement "round robin" scheduler interface to fixed-size ThreadPool

-----------------------------------

             Summary: [C++] Implement "round robin" scheduler interface to fixed-size ThreadPool 
                 Key: ARROW-8626
                 URL: https://issues.apache.org/jira/browse/ARROW-8626
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney
             Fix For: 1.0.0


Currently, when submitting tasks to a thread pool, they are all commingled in a common queue. When a new task submitter shows up, they must wait in the back of the line behind all other queued tasks.

A simple alternative to this would be round-robin scheduling, where each new consumer is assigned a unique integer id, and the schedule / thread pool internally maintains the tasks associated with the consumer in separate queues.
