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.

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

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.
