LOAD TESTING: Test with 1000+ bookings per structure to validate scalability. Verify cache hit rate under normal usage. 4. MONITORING: Add logging for cache misses to identify optimization opportunities. Monitor structure filter usage patterns. 5. FRONTEND INTEGRATION: Generate TypeScript types from OpenAPI schema: npx openapi-typescript http://localhost:8000/api/schema/ -o dashboard.d.ts 6. CACHE WARMING: Consider pre-warming cache during low-traffic periods for large structures. 7.
