Description
PP now uses PriorityThreadPool(PTP) that has 3 priority queues and supports Job re-scheduling(can happen if there is no space to service a primitive job request from EM).
PTP doesn't equally distribute computation resources b/w primitive jobs that belongs to different queries so that the variance of query timings is linear to number of simultaneous queries.
The suggestion is to implement a scheduling component that will try to fairly process mentioned primitive jobs.
