mik-laj opened a new pull request #7090: [AIRFLOW-6495] Load DAG only once when running a task using StandardTaskRunner URL: https://github.com/apache/airflow/pull/7090 If the process is created using a fork, it will share all loaded modules that were available before forking. This allows us to avoid loading DAG again. Sometimes the DAG loading process is costly because it do database queries or other costly operation, so we should limit it if possible. --- Issue link: WILL BE INSERTED BY [boring-cyborg](https://github.com/kaxil/boring-cyborg) - [X] Description above provides context of the change - [X] Commit message/PR title starts with `[AIRFLOW-NNNN]`.
