Airflow's scheduler ensures that tasks are triggered and executed according to their defined schedules. It monitors the scheduled tasks and launches new task instances based on the specified intervals, making it well-suited for frequent and time-sensitive operations.

Additionally, Airflow provides features such as task parallelism, distributed execution, and scalability, allowing you to handle a large number of frequent schedule-based operations efficiently.

So, if you have tasks or workflows that need to be executed at frequent intervals, even as often as every minute, Airflow provides the flexibility and robustness to handle such operations effectively.
