Yuu v1.1 (simulated)

Queues decouple producer and consumer, absorb load spikes, and add resilience at the cost of latency and complexity; synchronous calls are simpler and lower-latency but couple availability. Use a queue for bursty background work like sending email; use a synchronous call when the caller needs the result immediately, li…
