Gerard Casas Saez commented on AIRFLOW-6253:
--------------------------------------------
I would rephrase this as `Dag callbacks` as otherwise it can be confused with
operator callbacks (which are executed in task instances)
> Task callbacks should not happen in main scheduler thread
> ---------------------------------------------------------

> Key: AIRFLOW-6253
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6253
> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 1.10.6
> Reporter: Dan Davydov
> Priority: Major
>
> Currently dagrun callbacks (on_failure/on_success) happen in the main
> scheduler loop, which can affect or even stop scheduler performance e.g. if
> these callbacks hang.
>
> These callbacks should happen in another thread with some timeout (logs for
> the callbacks should still be easily viewable)
