Hi

I'm just trying to figure how the tasks are run in production. Am I right in thinking that the scheduler must be running, and if i am using celery than a worker must be running as well?

I just plan on using mysql at the moment. Do you recommend creating a init script to start the scheduler?

Cheers

You are absolutely right. A more modest single worker setup could run the scheduler with the LocalExecutor (as subprocesses). No Celery or message queue setup is needed in that case, but you are limited to a single worker.

Ok great thanks. I see the LocalExecutor can run tasks in parallel using multiprocessing. Will the scheduler be able to run tasks from different DAGs in parallel?

Yes.
