This is actual deletion - we issue DELETE on the TI row. The `TaskInstanceHistory` table has CASCADE delete, so all history records are permanently lost when the TI is deleted. When the scheduler recreates the TI, it gets a new UUID and try_number resets to 0, losing all previous execution history. -- This is an automated message from the Apache Git Service.
