----------------------------------------
Summary: Increase the default value of min_file_process_interval
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
Reporter: Keisuke Nishida
Priority: Minor
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?
