# Kir Shatrov - Designing Job Queue in Redis (Highlights) ![rw-book-cover|256](https://readwise-assets.s3.amazonaws.com/static/images/article2.74d541386bbf.png) ## Highlights - I stumbled upon a Redis library for Clojure which is called carmine. https://github.com/ptaoussanis/carmine - I was surprised to see that it has built-in message queue implementation. It’s only about 300 LOC and one file https://github.com/ptaoussanis/carmine/blob/master/src/taoensso/carmine/message_queue.clj - RPOPLPUSH carmine:mq:low:messages carmine:mq:low:messages # move the job from the head to tail within the same list, return <job id> - Celery, job queue framework in Python. Has lots of interesting features that we (again) miss in Ruby.
