What are some Message Queue patterns for handling spikes? I'm looking for ways to manage sudden surges in traffic.

Hey everyone, I've been thinking about how to best use message queues when traffic spikes. We're seeing occasional surges that overload our downstream services. What patterns or configurations do you find really work for handling these bursts? We don't want to lose messages or overwhelm our consumers. Any specific queue types or strategies that are great in these situations? I'm looking for practical advice, not just the obvious 'add more consumers'.
