github-actions[bot] opened a new pull request, #57175: URL: https://github.com/apache/airflow/pull/57175
When a user changed only the case of a DAG tag (e.g., 'dangerous' to 'DANGEROUS'), the dag-processor would crash with a duplicate key error on MySQL due to case-insensitive collation in the PRIMARY KEY. This occurred because SQLAlchemy executed INSERT operations before DELETE operations during the flush. The fix ensures DELETE operations complete before attempting INSERT operations by explicitly flushing and refreshing the tag relationship from the database. Fixes #56940 (cherry picked from commit 5013aad00b3b76e442861f8233c2691845f1fff1) Co-authored-by: Kaxil Naik <[email protected]> -- This is an automated message from the Apache Git Service.
