Redis Cache Service

Purpose

Generate Redis cache service with tenant-prefixed keys to prevent cross-tenant data leakage, TTL management for memory efficiency, and cache invalidation patterns.

When to Use

• Caching frequently accessed data
• Session storage
• Rate limiting
• Reducing database load
• Tenant-isolated caching

Patterns Enforced

Tenant-Prefixed Keys

Cache keys use format: tenant:{tenantId}:{key}

• Prevents cross-tenant cache pollution
• Enables tenant-wide cache clearing
• Isolates rate limit counters

TTL Management

• All cache keys have TTL
• Default TTL: 5 minutes (300 seconds)
• Session TTL: 24 hours (86400 seconds)
• No infinite TTL (prevents memory leaks)

Cache Invalidation

• Pattern-based deletion: delPattern('tenant:{tenantId}:*')
• Tag-based invalidation
• Automatic invalidation on updates

Usage Example

/skill cache-redis --name=User --methods='cacheUser,cachePermissions,clearUserCache'
