Sidekiq is the most powerful queuing solution, and it has a robust plugin ecosystem. The ability to configure it to have multiple queues is unique, and you don't need to install additional software to do it. It is easy to use and to configure, and there is a very active and diverse community behind it. No major issues. I like how it can handle lots of concurrent jobs at once without worrying about resource usage. I am also solving a problem of having to scale up my server quickly to support a large number of production apps. There is really no dislike. If I could, I would give this a 5 for its simplicity. It is easy to set up and use. I do not have any issues that I can think of right now. I haven't used all its features yet. The only thing I dislike is that I have to pay for it. It is a great tool to use and to get the most out of it, you have to pay for it. I am using it to process data in my API and to process my customer's API requests.
