The big idea
Redis is an in-memory store that returns data in microseconds. AI helps you decide what to cache, sets a sensible TTL, and warns you about the hardest problem in computing: cache invalidation.
Some examples
- Ask AI: 'Wrap this DB query in a Redis cache with a 5-minute TTL.'
- AI writes a cache-aside helper that handles misses cleanly.
- AI explains why you got stale data after an update.
- AI suggests using Upstash Redis on Vercel for serverless apps.
Try it!
Take an API route that hits a slow data source. Ask AI to add a Redis cache and show the before/after timing.
