-----------------------------------
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.
