Summary: Improve performance by avoid Unnecessary actions in
SchedulerJob.process_file()
Key: AIRFLOW-4173
URL: https://issues.apache.org/jira/browse/AIRFLOW-4173
Project: Apache Airflow
Issue Type: Improvement
Components: scheduler
Affects Versions: 1.10.2
Reporter: Xiaodong DENG
Assignee: Xiaodong DENG
In current implementation of *SchedulerJob.process_file()*
([https://github.com/apache/airflow/blob/068ded96cd279dcd51f5b6d1e96f09205ecf40c8/airflow/jobs.py#L1722-L1734),]
action '*dag = dagbag.get_dag(dag_id)*' is to be done no matter if dag_id is
pointing to a paused DAG. However, the result will not be used later if that
DAG is paused.
This is causing inefficiency.
