-----------------------------
Summary: add config for 'allow_multi_scheduler_instances' default
True
Key: AIRFLOW-6389
URL: https://issues.apache.org/jira/browse/AIRFLOW-6389
Project: Apache Airflow
Issue Type: New Feature
Components: scheduler
Affects Versions: 1.10.6
Reporter: t oo
airflow is often shared between users of varying experience levels. to prevent
a novice user causing a accidental denial of service to the scheduler (by
uploading huge dag which hogs all scheduler resources) i propose 2 new server
side configs:
# max num of tasks in a single dag: default say 250
# max num of dags: default say 500
To add to this airflow can't handle 18k tasks in single dag
(dag_processor_manager times out after 300 seconds) , but if i split up into 6
dags of 3k tasks each then it works.
