------------------------------------
Summary: 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
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)
