## Related Issue #50348 ---- This PR reintroduces the pre-import optimization for DAG parsing originally added in Airflow 2.6.0 (#30495) but missing in Airflow 3.0. It reduces DAG parsing time by importing common modules in the parent process before forking. While investigating Issue #50348, I developed a proposed solution and would appreciate feedback from the community. I understand the issue is currently assigned to @kevinhongzl, and I’m happy to collaborate or adjust direction based on their progress. Looking forward to feedback! <!-- Please keep an empty line above the dashes. --> --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#pull-request-guidelines)** for more information.
