I'm able to reliably force a DeadlockDetected exception by creating a DAG with many (i.e. over a hundred) concurrent tasks, setting `max_active_tasks_per_dag` to 75, setting `parallelism` to 100, triggering the DAG, waiting a couple minutes, then deleting the DAG Run. Maybe this is further evidence to @dstaple's proposed workaround limiting the lock to the `task_instance` table or at least a way to test if that workaround resolves this particular deadlock. -- This is an automated message from the Apache Git Service.
