7/14/2023 0 Comments Queue job![]() ![]() ![]() You can do advanced integrity checks like making sure the job is unique in the stack by specifying a unique id, or making sure two jobs will not overlap using the WithoutOverlapping job middleware, etc. If we keep the same example, here is a sneak peak of how to run a job: This means if you have a period of time you know you will have a lot of traffic, which will lead to lots of people to contact your company, you can decide to put more job runners to keep the stack low and help web users to receive their email confirmation faster. The other advantage is that you can scale them, because you can control how many job runners unstack your jobs. However, since they are unstacked one by one, you do not need to take care of command overlapping. In the other hand jobs requires a job runner to unstack them (Supervisor being the most popular when using Laravel - a documentation is available here to know how to set it up). This means you cannot determine in advance when the task will be performed. The server will take them one by one, when it has some time and resources. When commands are not bound to any specific time to send (meaning "perform these tasks as soon as possible"), we can see jobs as a stack of tasks to do. Setting up the Laravel Scheduler is easy since every servers comes with a cronjob runner (configurable using the crontab command). You can control how often you want your command to run:Įnter fullscreen mode Exit fullscreen mode In fact, Laravel requires to setup a "master" command (called the Scheduler), in order to regularily check for commands to run. This way, you do not block the loading of the success page for the web user, and the server will now be able to defer the task in a later time.Ĭommands in Laravel acts as a cron job. ![]() To fix this issue, you can ask your server to stack 2 tasks, one to send an email to your company inbox, another to send the confirmation email to the web user. Lastly, your users might have to wait longer before their page has finished loading before seeing the success confirmation page. This can also worsen the experience of other users navigating to other pages since the server will be busy both serving web pages and sending emails. GMail SMTP could also rate limit you and this means chances your emails will fail to send at some point. On a low traffic day, this might be quite fast for the user to receive its confirmation.īut if there is a thousands of contact sent per minutes, this might put your server in high risk of failure because you have an high CPU usage. Let us also imagine you are using GMail SMTP to send emails. Send a confirmation email to the web user.It has a text input for the email, another for the subject, and a textarea for the content. Think of it as ticket log, when you just stack them, and someone else is able to take the first in, process it, and move on to the next task.įor example, let us imagine your web app have a contact page. The main advantage is to be able to not block the end user with some long running tasks. Hi and welcome to this blog post where I would like to provide you with my experience of using commands and queue jobs within Laravel.Ĭommands and queue jobs help deferring tasks for a later time. ![]()
