Description

It would be nice to add method listDatabases(catalog) and listTables(catalog, database) in TableEnvironment. So that I can listDatabases with specified catalog and listTables with specified catalog and databases.
Otherwise I would always need to call useCatalog and useDatabase beforehand.
