> Key: AIRFLOW-1117
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1117
> Project: Apache Airflow
> Issue Type: Wish
> Components: scheduler
> Affects Versions: 1.8.0

> I observed high CPU usage after upgrading Airflow from 1.7.1.3 to 1.8.0.
> I found Airflow is loading DAG files repeatedly, which consumed most of the
> CPU time in my Airflow instance. I realized Airflow 1.8 introduced a new
> configuration variable {{min_file_process_interval}} with default value 0.
> This means Airflow reloads DAG files one after another without any interval.
> Can you increase the default value of {{min_file_process_interval}} to at
> least the same value of {{scheduler_heartbeat_sec}}, which is 5 seconds?
