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

What It Generates

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

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