In BullMQ, the number of job attempts or retries can be configured when adding a job to a queue. This can be useful when you want your jobs to be retried automatically if they fail.
Here is an example of how you can define a job with 3 attempts:
In this code,
attempts: 3 means that the job will be retried up to three times if it fails. The
backoff option sets how much time the queue should wait before retrying the job after a failure. In this case, it's set to a fixed delay of 5000 milliseconds (5 seconds).
If a job still fails after the maximum number of attempts, it's marked as failed and won't be processed again unless you manually retry it.
Please note that exception handling should be properly implemented in your job processing logic, so that exceptions are properly caught and handled. Uncaught exceptions might lead to unwanted behaviors.
