You'd want to think about using a message queue when, say, you have different parts of your system that need to talk to

hey everyone, ive been thinking a lot about system design lately, specifically around decoupling services. we use a few message queues already, but im wondering about the tipping point. when does the added complexity of a message queue outweigh the benefits of asynchronous communication and decoupling? what are the specific use cases or metrics that signal its time to introduce one?
