Redis Caching Best Practices

Overview

Redis caching reduces Firestore reads and improves response latency. However, Redis introduces concerns around max connections, network egress costs, and failure handling.

Key Principles:

• Fail fast, fail safe - Never block requests due to Redis issues
• Fire-and-forget writes - Cache writes should not slow down responses
• Circuit breaker - Temporarily disable Redis on connection issues
• Graceful degradation - Always fall back to Firestore
