Queue Retries and Failed Jobs: Making Background Work Reliable

Queues are powerful, but only if failures are handled properly. Common failure reasons: - network errors (email provider, payment gateway) - timeouts - temporary DB outages ## Configure retries on a job ```php public $tries = 3; public $backoff = [10, 30, 60]; public $timeout = 60; ``` ## Failed jobs table ```bash php artisan queue:failed-table php artisan migrate ``` ## Retry a failed job ```bash php artisan queue:retry all ``` ## Flow ```mermaid flowchart LR A[Job Dispatched] --> B[Worker] B --> C{Success?} C -->|Yes| D[Done] C -->|No| E[Retry] E --> C C -->|Still fails| F[Failed Jobs Table] ``` In the next tutorial, we will design caching invalidation strategies.
