Implementation Guidelines

• Offload Heavy Tasks: Move any logic taking >100ms to a Queued Job.
• ShouldQueue Interface: Add to Listeners for transparent async execution.
• Redis Driver: Use Redis for reliable and high-throughput queuing.
• Job Chaining: Use Bus::chain() for dependent sequential jobs.
• Job Batching: Use Bus::batch() for parallel task monitoring.
• Failures: Define failed() method in jobs to handle permanent errors.
• Monitoring: Use Laravel Horizon for real-time queue observability.

Anti-Patterns

• Blocking UX: No heavy logic in Request path: Always defer to Queues.
• Raw Models: No large job payloads: Pass model IDs, not full objects.
• Implicit Flow: No deep event-loop logic: Keep listener chains shallow.
• Silent Failures: No unmonitored queues: Ensure retries and alerts.
