Apache Spark reassigned AIRFLOW-1117: ------------------------------------- Assignee: Holden Karau's magical unicorn > 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 > Assignee: Holden Karau's magical unicorn > Priority: Minor > Attachments: screenshot-1.png > > > 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? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
