When should you think about using a message queue?

That's a good question. I'd say you should consider it when you've got different parts of your system that need to talk to each other, but they don't need to do it all at once. For example, if one service is sending out a bunch of emails and another is handling user requests, you don't want the email sending to slow down the user experience. A message queue can act as a buffer, holding those email tasks until the system is ready to process them. It also helps if you need to scale different parts of your application independently. You can add more workers to process messages without affecting the part that sends them. So, basically, when you need decoupling, asynchronous communication, and better reliability, a message queue is probably a good idea. hey folks, i've been thinking a lot about message queues lately. we're building a new system and i'm debating whether to introduce one early on, or wait until we actually hit scaling issues. on one hand, they seem great for decoupling services and handling traffic spikes. but they also add another component to manage and potentially another point of failure. when did you all decide to pull the trigger on using a message queue, and what were the main drivers for that decision? curious to hear your experiences
