Kevin Yang created AIRFLOW-2761:
-----------------------------------

             Summary: Parallelize Celery Executor enqueuing
                 Key: AIRFLOW-2761
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-2761
             Project: Apache Airflow
          Issue Type: Improvement
            Reporter: Kevin Yang


Currently celery executor enqueues in an async fashion but still doing that in a single process loop. This can slows down scheduler loop and creates scheduling delay if we have large # of task to schedule in a short time, e.g. UTC midnight we need to schedule large # of sensors in a short period.
