--------------------------------------------
[~xnuinside] if you have any spare time taking a detailed look at pr 3873, and
preferably running it somewhere if you could would be amazingly helpful.
> 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
> Priority: Major
>
> 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.
