Redis

Caching, data structures, and real-time patterns.

Key Naming Conventions

object-type:id:field        # Colon-separated hierarchy
user:1001:profile           # User profile
cache:api:/v2/products      # API response cache
session:abc123              # Session data
ratelimit:ip:10.0.0.1       # Rate limit counter
lock:order:7890             # Distributed lock

Keep keys short but readable. Colons are convention, not syntax. Avoid KEYS in production — use SCAN.
