What it does

This class serves as a data source provider for the customer_grid indexer in Magento 2.

It generates batches of customer data efficiently by loading customers in chunks (default 10,000 at a time) to avoid memory issues when reindexing large customer databases.

Developers would use this when working with customer grid indexing operations or when needing to iterate through large customer datasets in a memory-efficient manner.
