>    Affects Versions: 1.10.6

> 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 new 
> server side config: 
>  # max num of tasks in a single dag: if 0 then no limit
> 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.
