Prioritized
Jobs can also include a priority option. Using priorities, job's processing order will be affected by the specified priority instead of following a FIFO or LIFO pattern.
Adding prioritized jobs is a slower operation than the other types of jobs, with a complexity O(n) relative to the number of jobs waiting in the Queue.
Priorities goes from 1 to MAX_INT, whereas lower number is always higher priority than higher numbers.
Jobs without a priority assigned will get the least priority.
