Laravel's queues are one of the framework's most powerful features. With Vapor, you can continue writing and dispatching queued jobs exactly as you would in a traditional server-hosted Laravel application. The only difference is that Vapor will automatically scale your queue processing throughput on-demand within seconds:
use App\Jobs\ProcessPodcast; ProcessPodcast::dispatch($podcast);
When using Vapor, your application will use the AWS SQS service, which is already a first-party queue driver within Laravel. Vapor will automatically configure your deployed application to use this queue driver by injecting the proper Laravel environment variables. You do not need to perform any additional configuration.
Queued Job Time Limits
Currently, serverless applications on AWS may only process a single request (web or queue) for a maximum of 15 minutes. If your queued jobs take longer than 15 minutes, you will need to either chunk your job's work into smaller pieces or consider another deployment solution for your application. In addition, a queued job may not have a "delay" greater than 15 minutes.
Custom Queue Names
By default, Vapor will create an SQS queue that has the same name as your project and inject the proper environment variables to make this queue the default queue. If you would like to specify your own custom queue names that Vapor should create instead, you may define a
queues option in your environment's
vapor.yml configuration. The first queue in the list of queues will be considered your "default" queue and will automatically be set as the
SQS_QUEUE environment variable:
id: 2 name: vapor-laravel-app environments: production: queues: - emails - invoices
Disabling The Queue
If your application does not use queues, you may set the environment's
queues option to
id: 2 name: vapor-laravel-app environments: production: queues: false build: - 'composer install --no-dev'
By default, Vapor will allow your queue to process jobs at max concurrency, which is typically 1,000 concurrent jobs executing at the same time. If you would like to reduce the maximum queue concurrency, you may define the
queue-concurrency option in the environment's
id: 2 name: vapor-laravel-app environments: production: queue-concurrency: 50 build: - 'composer install --no-dev'
Queue Visibility Timeout
By default, if your queued job is not deleted or released within one minute of beginning to process, SQS will retry the job. To configure this "visibility timeout", you may define the
queue-timeout option in the environment's
vapor.yml configuration. For example, we may set this timeout to five minutes:
id: 2 name: vapor-laravel-app environments: production: queue-timeout: 300 build: - 'composer install --no-dev'
You may use the
queue-memory option in your environment's
vapor.yml configuration to define the memory that should be available to your queue worker Lambda function:
id: 2 name: vapor-laravel-app environments: production: queue-memory: 1024 build: - 'composer install --no-dev'
If you have installed the Vapor UI dashboard package, you may access the
/vapor-ui/jobs/metrics URI to monitor queue jobs.
Within the Vapor UI dashboard, you can monitor (in real-time) the number of processed jobs, failed jobs, and pending jobs for your Vapor application. In addition, it includes charts providing job statistics over the last 24 hours, allowing you to understand better the trends of your queue.
Furthermore, you may access the
/vapor-ui/jobs/failed to view the list of failed jobs, their details, job IDs, connections, queues, failures times, and other information about the jobs. From this screen, you may choose to retry or delete the failed job.
