Stop Notification Delays: Queue Worker Isolation

Short summary

The article explains queue worker isolation for high-volume notification systems using Laravel. When all notifications share one queue, bulk marketing blasts can block critical OTP messages. The solution is to split notifications into dedicated queue channels — a high-priority 'sync-critical' queue with many workers for transactional messages, and a 'bulk-marketing' queue with fewer workers for newsletters — ensuring time-sensitive alerts always process instantly.

• •Single shared queues cause head-of-line blocking when bulk jobs delay critical transactional notifications
• •Laravel's queue property lets you assign notifications to dedicated channels
• •Supervisor or Horizon configs run separate worker pools with different concurrency for each queue priority
