方法详细资料

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

另请参阅:

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.

isPartitioned

public boolean isPartitioned()

从接口复制的说明: CatalogMaterializedTable

Check if the table is partitioned or not.

指定者:

isPartitioned 在接口中 CatalogMaterializedTable

返回:

true if the table is partitioned; otherwise, false

getPartitionKeys

public List<String> getPartitionKeys()

从接口复制的说明: CatalogMaterializedTable

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 CatalogMaterializedTable

返回:

partition keys of the table

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. If a CatalogTable should not be serializable, an implementation can simply throw a runtime exception in this method.

指定者:

getOptions 在接口中 CatalogBaseTable

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

copy

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

从接口复制的说明: CatalogMaterializedTable

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

指定者:

copy 在接口中 CatalogMaterializedTable

返回:

a new copy of this table with replaced table options

copy

public CatalogMaterializedTable copy(CatalogMaterializedTable.RefreshStatus refreshStatus,
                                     String refreshHandlerDescription,
                                     byte[] serializedRefreshHandler)

从接口复制的说明: CatalogMaterializedTable

Returns a copy of this CatalogDynamicTable with given refresh info.

指定者:

copy 在接口中 CatalogMaterializedTable

返回:

a new copy of this table with replaced refresh info

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

getSnapshot

public Optional<Long> getSnapshot()

从接口复制的说明: CatalogMaterializedTable

Return the snapshot specified for the table. Return Optional.empty() if not specified.

指定者:

getSnapshot 在接口中 CatalogMaterializedTable

getDefinitionQuery

public String getDefinitionQuery()

从接口复制的说明: CatalogMaterializedTable

The definition query text of materialized table, text is expanded in contrast to the original SQL. This is needed because the context such as current DB is lost after the session, in which view is defined, is gone. Expanded query text takes care of this, as an example.

For example, for a materialized table that is defined in the context of "default" database with a query select * from test1, the expanded query text might become select `test1`.`name`, `test1`.`value` from `default`.`test1`, where table test1 resides in database "default" and has two columns ("name" and "value").

指定者:

getDefinitionQuery 在接口中 CatalogMaterializedTable

返回:

the materialized table definition in expanded text.

getDefinitionFreshness

public IntervalFreshness getDefinitionFreshness()

从接口复制的说明: CatalogMaterializedTable

Get the definition freshness of materialized table which is used to determine the physical refresh mode.

指定者:

getDefinitionFreshness 在接口中 CatalogMaterializedTable

getLogicalRefreshMode

public CatalogMaterializedTable.LogicalRefreshMode getLogicalRefreshMode()

从接口复制的说明: CatalogMaterializedTable

Get the logical refresh mode of materialized table.

指定者:

getLogicalRefreshMode 在接口中 CatalogMaterializedTable

getRefreshMode

public CatalogMaterializedTable.RefreshMode getRefreshMode()

从接口复制的说明: CatalogMaterializedTable

Get the physical refresh mode of materialized table.

指定者:

getRefreshMode 在接口中 CatalogMaterializedTable

getRefreshStatus

public CatalogMaterializedTable.RefreshStatus getRefreshStatus()

从接口复制的说明: CatalogMaterializedTable

Get the refresh status of materialized table.

指定者:

getRefreshStatus 在接口中 CatalogMaterializedTable
