CACHE_SCHEMA

Category: 01. AI / ML Hackathons
Section: Phase 2: Technical Blueprint

Act as a backend/DevOps engineer.
Using the System Architecture and API Specification, create a Caching Strategy document for this AI hackathon project.

ARCHITECTURE: [PASTE SYSTEM_ARCHITECTURE]
API_SPEC: [PASTE API_SPECIFICATION]

Provide:
1. Cache strategy (Redis, In-memory, Semantic Cache)
2. Cache key structure (How to uniquely identify a request)
3. TTL (Time-to-live) for different types of data
4. Cache invalidation strategy (When to clear the cache)
5. What to cache (AI responses, embeddings, user sessions)
6. What NOT to cache (Personal data, sensitive prompts)
7. Fallback if cache fails
8. A simple implementation checklist

Explain how caching will save money and make the demo run faster.
