Resilient Storage Layer

Multi-backend storage with automatic failover. Redis primary, database secondary, memory fallback. Circuit breakers per backend. Health-aware routing.

When to Use This Skill

• Building systems that can't afford storage downtime
• Need graceful degradation when Redis or database is unavailable
• Implementing distributed locks that must work even during partial outages
• Any caching layer that needs high availability

Core Concepts

The resilient storage layer provides:

• Multiple storage backends with priority ordering
• Automatic failover when a backend fails
• Circuit breakers to prevent cascading failures
• Health checks to detect and recover from outages
• Memory fallback that's always available
