Attribute\Collection
Magento\Customer\Model\ResourceModel\Attribute\Collection
What it does
This collection class is used to retrieve and manage customer attribute records from the database.
Developers use this when they need to fetch, filter, or manipulate multiple customer EAV attributes, such as getting all customer attributes for configuration, form building, or data migration.
It extends Magento's base EAV attribute collection and automatically sets the entity type to 'customer' and configures website-specific attribute settings.
