The raw data when ingested may not have the schema in desired structure, and may get stored in its native format in Data Lake. Data must exist in a target schema structure when the data is being queried from the storage. In order to convert/res-structure the data from its native schema to the target schema, the data needs to be processed. In our case, the final batch views when created will have a defined schema against that the views are build and exposed.
