Description

In the latest priority scheduling design, we need to dynamically determine the priority of a queue.

There are several possible modes:

 

• Leaf queues
  • priority.policy = default
    • Priority is defined as the maximum priority of any applications with pending tasks + priority.offset, or MIN_INT32 (-2^32) if no applications have pending tasks
  • priority.policy = fence
    • Priority is always equal to priority.offset, or MIN_INT32 if no applications have pending tasks
• Parent queues
  • priority.policy = default
    • Priority is defined as the maximum priority of any child queues + priority.offset
  • priority.policy = fence
    • Priority is always equal to priority.offset or MIN_INT32 if no pending tasks exist

We should expose this as a property of a queue in REST API calls as well.
