Expert guidance for Redis - the in-memory data structure store used as cache, message broker, and database with microsecond latency.

❌ Using Redis as primary database: Use for caching/sessions ❌ Not setting TTL on cache keys: Causes memory bloat ❌ Using KEYS in production: Use SCAN instead ❌ Large values in keys: Keep values small (<1MB) ❌ No monitoring: Track memory, latency, hit rate ❌ Synchronous blocking operations: Use async operations

❌ Not handling connection failures: Implement retry logic ❌ Storing large collections in single key: Split into multiple keys
