GitHub user pykenny edited a comment on the discussion: Need help understanding total number of Dags oscillating on UI
When scheduler and DAG processing runs independently (enable `standaline_dag_processor`), scheduler has no access to DAG definition folders, and need some protocol between DAG processor to know when a DAG definition gets removed from the file system and should be deactivated. Standalone DAG processor tries its best to send the information (discovering new ones/updating existing ones/removal) to scheduler but still has some limitation, hence `dag_stale_not_seen_duration` is a bottom line to make final decision when DAG scheduler stops receiving any information about some managed DAG from DAG processor. `min_file_process_interval`, on the other hand, is the last line of defense for DAG parser to ensure a DAG definition's freshness by force parsing definition file constantly, in case it fails to detect change in the file system correctly.
