Hi Thomas,

1. Yes, they are stored in the system collection _jobs. System collections 
are usually replicated to at least one other node.
2. The behavior of a failed job can be defined when creating a job (see docs 
).
 
Failed jobs will not impact the queue.
3. Jobs aren't purged automatically, you have to delete them manually (see 
docs 
).
 
This can also be done with a periodic job.

Best
Mark
