@PublicEvolving
public class CatalogDescriptor
extends Object

Describes a Catalog with the catalog name and configuration.

A CatalogDescriptor is a template for creating a Catalog instance. It closely resembles the "CREATE CATALOG" SQL DDL statement, containing catalog name and catalog configuration. A CatalogDescriptor could be stored to CatalogStore.

This can be used to register a catalog in the Table API, see TableEnvironment#createCatalog(String, CatalogDescriptor).
