Intelligent Caching

Multi-layer caching with type-specific TTLs and get-or-generate pattern.

When to Use This Skill

• Different content types need different freshness
• Expensive generation (AI, aggregations)
• Need persistence across restarts
• Want to track generation time for optimization

Core Concepts

Production caching needs:

1. Type-specific TTLs - Different content, different freshness
2. Two-layer cache - Memory for speed, DB for persistence
3. Get-or-generate - Single function handles everything
4. Generation timing - Track for optimization
