java.lang.Object

org.apache.flink.table.catalog.ResolvedCatalogTable

所有已实现的接口:

CatalogBaseTable, CatalogTable, ResolvedCatalogBaseTable<CatalogTable>

@PublicEvolving
public final class ResolvedCatalogTable
extends Object
implements ResolvedCatalogBaseTable<CatalogTable>, CatalogTable

A validated CatalogTable that is backed by the original metadata coming from the Catalog but resolved by the framework.

Note: Compared to CatalogTable, instances of this class are serializable into a map of string properties.

方法详细资料

getOrigin

public CatalogTable getOrigin()

从接口复制的说明: ResolvedCatalogBaseTable

Returns the original, unresolved metadata object from the Catalog.

This method might be useful if catalog-specific object instances should be directly forwarded from the catalog to a factory.

指定者:

getOrigin 在接口中 ResolvedCatalogBaseTable<CatalogTable>

getResolvedSchema

public ResolvedSchema getResolvedSchema()

从接口复制的说明: ResolvedCatalogBaseTable

Returns a fully resolved and validated ResolvedSchema.

Connectors can configure themselves by accessing ResolvedSchema.getPrimaryKey() and ResolvedSchema.toPhysicalRowDataType().

指定者:

getResolvedSchema 在接口中 ResolvedCatalogBaseTable<CatalogTable>

toProperties

public Map<String,String> toProperties()

从接口复制的说明: CatalogTable

Serializes this instance into a map of string-based properties.

Compared to the pure table options in CatalogBaseTable.getOptions(), the map includes schema, partitioning, and other characteristics in a serialized form.

指定者:

toProperties 在接口中 CatalogTable

getOptions

public Map<String,String> getOptions()

从接口复制的说明: CatalogBaseTable

Returns a map of string-based options.

In case of CatalogTable, these options may determine the kind of connector and its configuration for accessing the data in the external system. See DynamicTableFactory for more information.

指定者:

getOptions 在接口中 CatalogBaseTable

getUnresolvedSchema

public Schema getUnresolvedSchema()

从接口复制的说明: CatalogBaseTable

Returns the schema of the table or view.

The schema can reference objects from other catalogs and will be resolved and validated by the framework when accessing the table or view.

指定者:

getUnresolvedSchema 在接口中 CatalogBaseTable

ResolvedCatalogTable, ResolvedCatalogView

getComment

public String getComment()

从接口复制的说明: CatalogBaseTable

Get comment of the table or view.

指定者:

getComment 在接口中 CatalogBaseTable

返回:

comment of the table/view.

copy

public CatalogBaseTable copy()

从接口复制的说明: CatalogBaseTable

Get a deep copy of the CatalogBaseTable instance.

指定者:

copy 在接口中 CatalogBaseTable

返回:

a copy of the CatalogBaseTable instance

getDescription

public Optional<String> getDescription()

从接口复制的说明: CatalogBaseTable

Get a brief description of the table or view.

指定者:

getDescription 在接口中 CatalogBaseTable

返回:

an optional short description of the table/view

getDetailedDescription

public Optional<String> getDetailedDescription()

从接口复制的说明: CatalogBaseTable

Get a detailed description of the table or view.

指定者:

getDetailedDescription 在接口中 CatalogBaseTable

返回:

an optional long description of the table/view

isPartitioned

public boolean isPartitioned()

从接口复制的说明: CatalogTable

Check if the table is partitioned or not.

指定者:

isPartitioned 在接口中 CatalogTable

返回:

true if the table is partitioned; otherwise, false

getPartitionKeys

public List<String> getPartitionKeys()

从接口复制的说明: CatalogTable

Get the partition keys of the table. This will be an empty set if the table is not partitioned.

指定者:

getPartitionKeys 在接口中 CatalogTable

返回:

partition keys of the table

copy

public ResolvedCatalogTable copy(Map<String,String> options)

从接口复制的说明: CatalogTable

Returns a copy of this CatalogTable with given table options options.

指定者:

copy 在接口中 CatalogTable

返回:

a new copy of this table with replaced table options
