Does Yii2 send a query to the database when using such a string?

Question

Yii

Hello. The following question arose. I can access the user model in the following way
Yii::$app->user->identity;
Question with the following. When executing this code, is the model already in this variable or is there a query to the database during execution?
Thanks in advance to all who respond.
