Do Periodic & Repeated Jobs keep the same Job ID when repeated? Redis RQ-Scheduler

Question

Let's say I had a job which is scheduled to run every 3 hours.

job = scheduler.schedule(
    scheduled_time=datetime.utcnow(),
    func=func,
    interval=10800,
    repeat=None
)

jobID = job.id

On the fifth time it runs, will it have the same Job ID as it does on the first time it's added to the scheduler - or does it change?

Answer 1

in short no it will not. You will infact notice that even if you job has the same date time object upto the microsecond level, it still throws a different job ID.

Heres my implementation and experience

def test():
      print("HELLO")

today=datetime.datetime.today()
today=today.replace(hour=10,minute=15,second=0,microsecond=0)
s1=Scheduler(connection=Redis())


print(today)
s1.schedule(scheduled_time=today,func=test,args=[],interval=10,repeat=None)

jobs1=s1.get_jobs()

for job in jobs1:
      #s1.cancel(job)
      print("first",job,job.id)

And heres the output:
