Yii2 使用updateAll批量修改不觸發 afterSave()

afterSave() is thought for a single record. updateAll() handles many records in a completly different way. So you cannot use afterSave() this way. Imagine: when you update thousands of records this way, the afterSave() methods would need to be executed for each record - you would probably need something like afterSaveAll() that gets called once and that does only a single (or some few) further update, right?
