So, if I have for example 3 dynos, that means that I have 3 nodes, so in my case, instead of having a queue of limit 1, the global limit is 3?
That’s correct. Each node will run up to the limit you specify. If you absolutely must run a single job at a time you can dynamically determine whether to start a queue when your app starts
You can rely on consistent naming to do this by checking the DYNO environment variable (i.e. web.1).
I would advise against relying on global limits though because you’ll still have overlap during rolling deploys and the implementation may be fragile.
