One execution per queue/job class

[airled]

Hi. I've tried to search for this in different places but I can't find exactly what I need. So I have several jobs, say Job1 and Job2. And I have a sidekiq process with concurrency set to 2. I need sidekiq to handle simultaneously one job per job class. So simultaniously {job1, job2} is ok. But running {job1, job1} or {job2, job2} at the same time is not ok. Yes, I understand that I can use queue1 for Job1 and queue2 for Job2 and then run two sidekiq processes using concurrency 1 with -q queue1 for first process and -q queue2 for second. But what if I have such jobs, say, 20? I don't want to run 20 sidekiq processes for each job. Is it possible somehow to handle it within a single sidekiq process? Thanks in advance.

A single threaded Capsule is one possibility but I’d advise you to author your jobs in a more concurrent-friendly fashion.

This sidekiq extension implements exactly what you described https://github.com/ixti/sidekiq-throttled

@mperham @freemanoid Thank you so much for your responses. Seems like both Capsules and Throttle extension are exactly what I need. @mperham I set freemanoid's post as answer since the extension is more flexible. But using Capsules suits better for my goal.
