On big installation the "get_dag_runs" endpoint to list all the dagruns in the UI is taking a long time to return a response. The critical part of the code is the actual db query. Most likely due to the number of joins creating rows explosion. We need to optimize the query, most likely by double checking the eager loading options and verify that there is no row explosion (joinedload vs selectinload) cause by a wrong option. Also we can add `load_only` to limit the number of columns selected in each joins. https://github.com/apache/airflow/blob/4e75919198be6b8e4d3ac52656a9b74e0e73b097/airflow-core/src/airflow/api_fastapi/core_api/routes/public/dag_run.py#L387-L421 Also needs investigation to check if an extra index could help. https://github.com/user-attachments/assets/43505ed2-fef8-45f3-9865-78a1f32509dc ### Committer - [x] I acknowledge that I am a maintainer/committer of the Apache Airflow project. -- This is an automated message from the Apache Git Service.
