org.apache.flink.table.catalog

Class ConnectorCatalogTable<T1,T2>

java.lang.Object

org.apache.flink.table.catalog.AbstractCatalogTable

org.apache.flink.table.catalog.ConnectorCatalogTable<T1,T2>

Type Parameters:

T1 - type of the produced elements by the TableSource

T2 - type of the expected elements by the TableSink

All Implemented Interfaces:

org.apache.flink.table.catalog.CatalogBaseTable, org.apache.flink.table.catalog.CatalogTable

@Internal
public class ConnectorCatalogTable<T1,T2>
extends AbstractCatalogTable

A CatalogTable that wraps a TableSource and/or TableSink. This allows registering those in a Catalog. It can not be persisted as the source and/or sink might be inline implementations and not be representable in a property based form.
