@Internal
public class CatalogManagerCalciteSchema
extends FlinkSchema

Bridge between the CatalogManager and the Schema. This way we can query Flink's specific catalogs from Calcite.

The mapping for Catalogs is modeled as a strict two-level reference structure for Flink in Calcite, the full path of objects is of format [catalog_name].[db_name].[meta-object_name].
