Laravel Job Duplication
问题
我目前在我的Laravel应用程序中遇到了作业复制的问题。我有一个作业，我只调度一次 dispatch(new SendFirebaseNotificationJob($data));，但在监视 artisan queue:work --sleep=3 --tries=0 --backoff=3 --max-time=3600 命令时，有时会看到作业处理多次触发（4或6次）。
我尝试找出问题的原因，但到目前为止还没有找到解决方案。
我将不胜感激任何关于如何解决此问题的建议或指导。如果有人曾经遇到类似的问题或对我可以尝试的有任何建议，我将非常感激。
谢谢您提前的帮助。

I'm currently experiencing an issue with job duplication in my Laravel application.
I have a job that I dispatch once dispatch(new SendFirebaseNotificationJob($data));, but while monitoring the artisan queue:work --sleep=3 --tries=0 --backoff=3 --max-time=3600 command, I sometimes see that the job handle has been triggered multiple times (4 or 6 times).

I've tried to identify the cause of the issue, but I haven't been able to find a solution so far.
I would appreciate any advice or guidance on how to resolve this issue. If anyone has experienced a similar problem or has any suggestions on what I could try, I would be grateful for any input.
Thanks in advance for your help.
Checking if the job is idempotent: I reviewed the job code to ensure that it can not be executed multiple times, i deleted the job request from the DB so it will not be dispatched.
However, I am still experiencing job duplication in my Laravel application. I expected the job to be executed only once

你可以使用WithoutOverlapping作业中间件来防止多次分派作业和作业重叠 - https://laravel.com/docs/10.x/queues#preventing-job-overlaps
在需要确保仅分派一次的作业上使用它是一个好的做法。
英文:
You can prevent dispatching job multiple times and job overlaps with WithoutOverlapping job middleware - https://laravel.com/docs/10.x/queues#preventing-job-overlaps
It is good practice to use it on jobs that you need to be sure are dispatched only once.
