Frequently Asked Questions
How do you prevent a Redis cache miss from overwhelming PostgreSQL during traffic spikes?
I implement single-flight request coalescing (so only one worker recomputes the missing key while concurrent requests await the same promise) alongside stale-while-revalidate TTL jitter.
