DefaultDynamicTableContext

                                  ResolvedCatalogTable catalogTable,
                                  org.apache.flink.configuration.ReadableConfig configuration,

方法详细资料

getObjectIdentifier

public ObjectIdentifier getObjectIdentifier()

从接口复制的说明: DynamicTableFactory.Context

Returns the identifier of the table in the Catalog.

指定者:

getObjectIdentifier 在接口中 DynamicTableFactory.Context

getCatalogTable

public ResolvedCatalogTable getCatalogTable()

从接口复制的说明: DynamicTableFactory.Context

Returns the resolved table information received from the Catalog.

The ResolvedCatalogTable forwards the metadata from the catalog but offers a validated ResolvedSchema. The original metadata object is available via ResolvedCatalogTable.getOrigin().

In most cases, a factory is interested in the following two characteristics:

 // get the physical data type to initialize the connector
 context.getCatalogTable().getResolvedSchema().toPhysicalRowDataType()

 // get primary key information if the connector supports upserts
 context.getCatalogTable().getResolvedSchema().getPrimaryKey()
 

Other characteristics such as metadata columns or watermarks will be pushed down into the created DynamicTableSource or DynamicTableSink during planning depending on the implemented ability interfaces.

指定者:

getCatalogTable 在接口中 DynamicTableFactory.Context

getConfiguration

public org.apache.flink.configuration.ReadableConfig getConfiguration()

从接口复制的说明: DynamicTableFactory.Context

Gives read-only access to the configuration of the current session.

指定者:

getConfiguration 在接口中 DynamicTableFactory.Context

getClassLoader

public ClassLoader getClassLoader()

从接口复制的说明: DynamicTableFactory.Context

Returns the class loader of the current session.

The class loader is in particular useful for discovering further (nested) factories.

指定者:

getClassLoader 在接口中 DynamicTableFactory.Context

isTemporary

public boolean isTemporary()

从接口复制的说明: DynamicTableFactory.Context

Whether the table is temporary.

指定者:

isTemporary 在接口中 DynamicTableFactory.Context
