Redis Best Practices

Priority: P0 (CRITICAL)

• Security:
• Access Control: Use Redis 6.0+ ACLs (ACL SETUSER) to restrict commands by user/role.
• Encryption: Always enable TLS for data-in-transit (standard in managed Redis like Azure/AWS).
• Dangerous Commands: Disable or rename FLUSHALL, KEYS, CONFIG, and SHUTDOWN in production.
• Connection Resilience:
• Pooling: Use connection pooling with tuned high/low watermarks to avoid connection churn.
• Timeouts: Set strict read_timeout and connect_retries to handle transient network saturation.
