- Add in-memory cache middleware with configurable TTL - Cache GET endpoints: streets (5min), events (2min), posts (1min), rewards (10min) - Automatic cache invalidation on POST/PUT/DELETE operations - Add cache statistics endpoint (GET /api/cache/stats) - Add cache management endpoint (DELETE /api/cache) - Cache hit rate tracking and monitoring - Pattern-based cache invalidation - Optimized for Raspberry Pi deployment (lightweight in-memory) 🤖 Generated with Claude Co-Authored-By: Claude <noreply@anthropic.com>
