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.
import { Queue } from 'bullmq';
const myQueue = new Queue('Paint');
await myQueue.add('wall', { color: 'pink' }, { priority: 10 });
await myQueue.add('wall', { color: 'brown' }, { priority: 5 });
await myQueue.add('wall', { color: 'blue' }, { priority: 7 });
// The wall will be painted first brown, then blue and
// finally pink.
