Magento\Indexer\Model\Source\DataInterface
What it does
This interface defines a contract for data source providers in Magento's indexer system.
Developers implement this interface when creating custom data sources that feed information into indexers, allowing them to standardize how data is retrieved and processed during index operations.
It's typically used when building custom indexers that need to fetch data from specific sources based on provided field criteria.
