title: How to disable retry in celery?
body: <p>I am running a celerybeat scheduler every 15 mins where I need to fetch data from API (rate limit = 300 requests/min max) and store the results into the database. I would like to fetch the urls in parallel subject to rate limits at the same time. If any worker fails here, I don't want to retry since I will ping again in 15 mins. Any suggestions on how this can be accomplished in celery. </p>
  
  <pre><code>@celery.task(bind=True)
  def fetch_store(self):
      start = time()
      return c.chain(c.group(emap.s() for _ in range(2000)), ereduce.s(start)).apply_async()
  
  @celery.task(rate_limit='300/m')
  def fetch():
      #... requests data from external API
      return data
  
  @celery.task
  def store(numbers, start):
      end = time()
      logger.info("Received" + numbers + " " + (end - start)/1000 + "seconds")
  </code></pre>
