Redis Best Practices

Data Modeling

• Use appropriate data structures
• Use meaningful key names
• Implement key expiration
• Use hashes for objects
• Use sorted sets for leaderboards

Caching Patterns

• Cache-aside (lazy loading)
• Write-through for consistency
• Write-behind for performance
• Set appropriate TTLs
• Handle cache misses gracefully

Performance

• Pipeline commands
• Use Lua scripts for atomic ops
• Avoid large keys/values
• Use SCAN instead of KEYS
• Monitor memory usage

Reliability

• Enable persistence (RDB+AOF)
• Use Redis Cluster for HA
• Implement proper error handling
• Set maxmemory policy
• Monitor with RedisInsight

Security

• Enable authentication
• Use TLS encryption
• Bind to specific interfaces
• Rename dangerous commands
• Limit client connections
