What it does
This class serves as a processor for the Customer Grid indexer in Magento 2.
Developers use this processor to trigger reindexing of customer data in the admin grid, ensuring that customer information displayed in the backend is up-to-date.
It extends the framework's AbstractProcessor to provide customer-specific indexing functionality that can be called programmatically or scheduled.
