Interface Summary

Interface	Description
Catalog	This interface is responsible for reading and writing metadata such as database/table/views/UDFs from a registered catalog.
CatalogBaseTable	A common parent that describes the unresolved metadata of a table or view in a catalog.
CatalogChange	CatalogChange represents the modification of the catalog.
CatalogDatabase	Interface of a database in a catalog.
CatalogFunction	Interface for a function in a catalog.
CatalogMaterializedTable	Represents the unresolved metadata of a materialized table in a Catalog.
CatalogModel	Interface for a model in a catalog.
CatalogPartition	Represents a partition object in catalog.
CatalogStore	Represents the storage where persists all Catalogs.
CatalogTable	Represents the unresolved metadata of a table in a Catalog.
CatalogView	Represents the unresolved metadata of a view in a Catalog.
Constraint	Integrity constraints, generally referred to simply as constraints, define the valid states of SQL-data by constraining the values in the base tables.
DataTypeFactory	Factory for creating fully resolved data types that can be used for planning.
Index	An index is a copy of selected columns of data, from a table, that is designed to enable very efficient search.
ModelChange	ModelChange represents the modification of the model.
ResolvedCatalogBaseTable<T extends CatalogBaseTable>	A common parent that describes the resolved metadata of a table or view in a catalog.
ResolvedCatalogModel	A validated CatalogModel that is backed by the original metadata coming from the Catalog but resolved by the framework.
SchemaResolver	Resolves a Schema to a validated ResolvedSchema.
StagedTable	The StagedTable is designed to implement Flink's atomic semantic for CTAS(CREATE TABLE AS SELECT) and RTAS([CREATE OR] REPLACE TABLE AS SELECT) statement using a two-phase commit protocol.
TableChange	TableChange represents the modification of the CatalogBaseTable.
TableChange.CatalogTableChange	TableChange.CatalogTableChange represents the modification of the CatalogTable.
TableChange.ColumnPosition	The position of the modified or added column.
TableChange.MaterializedTableChange	TableChange.MaterializedTableChange represents the modification of the materialized table.
TemporaryOperationListener	This interface is for a Catalog to listen on temporary object operations.
