> Key: AIRFLOW-3775
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3775
> Project: Apache Airflow
> Issue Type: Wish
> Components: scheduler
> Reporter: Abhishek Sharma
> Priority: Major

>
> Currently, airflow scheduler picks DAGs for execution based on cron string
> mentioned in the schedule.
> I have a requirement in which I want to trigger the DAGs based on the event.
> Currently, I am managing such requirement by running an application which
> triggers DAGs when an event occurs. DAGs schedule with such requirement is
> NONE and concurrency is 1.
> Airflow considers all runs as manual triggers, and Airflow UI is messed up
> for that. Also, multiple applications required for triggering DAGs based on
> different condition.
> I propose to have to multiple schedulers support in Airflow, and like queue
> feature at a task level, we should have the scheduler option to at the task
> level, which by default would be time-based however on providing specific
> value will be picked by that instance of the scheduler.
