Redis Caching & Queues

When to use this skill

• Implementing caching (KV store).
• Setting up background job queues.
• Configuring Redis persistence.

1. Caching Strategies

• TTL: Always set a Time-To-Live (TTL) for cache keys to prevent memory leaks.
• Keys: Use namespaced keys app:user:123 to avoid collisions.
• Invalidation: Prefer short TTLs over complex invalidation logic where possible.

2. Queues

• Laravel: Use redis driver for queue. Run php artisan horizon for monitoring.
• Python: Use Celery or RQ backed by Redis.
• Atomicity: Use LPUSH/RPOP or Streams for reliable messaging.

3. Configuration

• Maxmemory: Configure maxmemory and eviction policy (allkeys-lru for cache, noeviction for queues).
• Persistence: Enable RDB snapshots for queues; AOF for higher durability needs.
