Different queues with one job per worker

[wazirsoft]

I am having four different queues listening and running separate operations as typical queues do. Currently if each queue get one job all these four jobs would start processing at once and just on a single worker. I don't want to do this as each queue is resource intensive.

I can't merge all these four jobs into single queue to fix this concurrency issue. The reason is, I am using Arena and would like to see all the jobs separated by the queues like Arena let you see.

Do I have any other approach I can take to solve this problem?
