mongodb\Cache $db

$db public property

The MongoDB connection object or the application component ID of the MongoDB connection. After the Cache object is created, if you want to change this property, you should only assign it with a MongoDB connection object. Starting from version 2.0.2, this can also be a configuration array for creating the object.

public yii\mongodb\Connection|array|string $db = 'mongodb'
