[GitHub] [airflow] uranusjr commented on pull request #25404: Removed interfering force of index.

   Hmm, this line was actually introduced in #2021 to fix a performance issue in the first place. Unfortunately context is sparse on things this old, but I wonder what changed between then and now that the “normal” case is not slower now—we did change TaskInstance’s primary key in 2.2 to use `run_id` instead of `execution_date`, and also added an explicit foreign key to DagRun (which I think is relevant because this query joins that table). Do you think any of these would explain the difference?
