-The Simple Mode takes a different approach by extending the deduplication duration until the job's completion or failure. This means as long as the job remains in an incomplete state (neither succeeded nor failed), any subsequent job with the same deduplication ID will be ignored.

 This class automatically moves delayed jobs back to the waiting queue when it is the right time to process them. It also automatically checks for stalled jobs (i.e. detects jobs that are active but where the worker has either crashed or stopped working properly). [Stalled jobs](jobs/stalled.md) are moved back or failed depending on the settings selected when instantiating the class.

 {% endhint %}
 
 The reason for having this functionality in a separate class instead of in the workers (as in Bull 3.x) is because whereas you may want to have a large number of workers for parallel processing, for the scheduler you probably only want a couple of instances for each queue that requires delayed or stalled checks. One will be enough but you can have more just for redundancy.
