Support for sharing a persistent job store between multiple schedulers appears to be planned for Running their own scheduler then this can result in jobs being missed or executed multiple times, as well as duplicateĮntries being created in the DjangoJobExecution table. It is quite common to start up many webserver worker process in productionĮnvironments in order to scale and handle large volumes of user traffic. Limitation might require a bit of thought. Other words, different schedulers won't be able to tell if a job has already been run by another scheduler, and changingĪ job's scheduled run time directly in the database does nothing unless you also restart the scheduler).ĭepending on how you are currently doing your That would enable the scheduler to be notified when a job has been added, modified, or removed from a job store (in This limitation is due to the fact that APScheduler does not currently haveĪny interprocess synchronization and signalling scheme Scheduler actively running at a particular point in time. PLEASE NOTE: the trade-off of this simplicity is that you need to be careful to ensure that you have only ONE Handful of tasks on a fixed execution schedule.
