I was having some problems using carmine to work with Redis pubsub when there was a lot of pub and sub. I tried to fix the problem, but it was taking more time than it should.
I "resorted" to using jeris (Redis driver for Java) directly, and the problem I had was solved, but using Java in Clojure is not a friendly experience (interop is annoying).
I am creating a simple library abstracting all the complexity of using Java/Clojure interop into a library to work with Redis queues (including pubsub and queue).
https://github.com/moclojer/clj-rq com.moclojer/rq (aka clj-rq), RQ (Redis Queue) is a simple Clojure package for queueing jobs and processing them in the background with workers. It is backed by Redis and it is designed to have a low barrier to entry, inspired by python-rq.
still in development, but I'm already using it in moclojer cloud https://moclojer.com/
