If `DagBag.get_dag()` is called currently, it will return the DAG even if the DAG does not exist in `serialized_dag` table. This PR changes that logic to remove the dag from local cache too when `DagBag.get_dag()` is called. This happens after `min_serialized_dag_fetch_secs`.

We need to run full set of tests for this PR to merge
label
Jun 11, 2021
The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease. |
