John Arnold commented on AIRFLOW-2156:

This seems like a pretty easy candidate for multiprocessing.

>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-2156
>             Project: Apache Airflow
>          Issue Type: Improvement
>          Components: celery
>            Reporter: Dan Davydov
>            Assignee: Dan Davydov
>            Priority: Major
> The CeleryExecutor doesn't currently support parallel execution to check task 
> states since Celery does not support this. This can greatly slow down the 
> Scheduler loops since each request to check a task's state is a network 
> request.
> The Celery Executor should parallelize these requests.
