public class MetadataControllerBatch
extends AbstractBinaryRecordBatch<MetadataControllerPOP>

Terminal operator for producing ANALYZE statement. This operator is responsible for converting obtained metadata, fetching absent metadata from the Metastore and storing resulting metadata into the Metastore.

This operator has two inputs: left input contains metadata and right input contains statistics metadata.
