Not possible to abort an execution in case of a failed service execution

[FlorianDue]

The PFDL Scheduler schedules services, which are then executed on some asset. In case that the service execution succeedes, a notification is send to the PFDL scheduler, which then triggers an event (Event(event_type="service_finished", data={"service_id": service_uuid}).

However, there is no specified behavior in case that an service execution fails and the process execuion should be aborted.

Here, it would be great if a custom event type could be provided, that stops the scheduler execution.

For example the event could be Event(event_type="service_failed", data={"service_id": service_uuid}) to stop the scheduler.

Another nice feature would be an Event Type to reschedule the service execution, so that the scheduler again starts the failed service execution. An event coul be e.g., Event(event_type="service_repeat", data={"service_id": service_uuid})
