title: python apschedular RedisJobStore not storing jobs in redis cache
body: <p>That is my python code: All jobs are triggering at right time but not stored as redis cache. If restart the program, cannot schedule pending jobs. What I am doing wrong?</p>
  
  <pre><code>from apscheduler.jobstores.redis import RedisJobStore
  from apscheduler.executors.pool import ThreadPoolExecutor, ProcessPoolExecutor
  
  if __name__ == '__main__':
  
      jobstores = {
          'redis': RedisJobStore(jobs_key='dispatched_trips_jobs', run_times_key='dispatched_trips_running', host='localhost', port=6379)
      }
      executors = {
          'default': ThreadPoolExecutor(100),
          'processpool': ProcessPoolExecutor(5)
      }
  
      scheduler = BackgroundScheduler(jobstores=jobstores, executors=executors)
  
  
      scheduler.start()
  
      while True:
          pass
