Redis Caching

Implement Redis as a production support layer, not as a second database.

When to Use

• Add cache-aside or write-through caching around Prisma or API reads.
• Protect expensive routes with rate limiting.
• Store short-lived sessions, verification state, locks, or counters.
• Add pub/sub or stream-backed event fanout.
• Review Redis key design, TTLs, invalidation, or connection handling.

For BullMQ job queue architecture, use nestjs-queue-architect instead of duplicating queue patterns here.
