Class TableInfo

Object

org.apache.spark.sql.connector.catalog.TableInfo

public class TableInfo
extends Object

Metadata describing a data-source table: its columns, properties, partitioning and constraints. Spark realizes a TableInfo into a Table via DelegatingTable; a catalog that has its own Table object returns that instead. Views are described by the sibling View, which -- unlike a table -- is itself a Relation because Spark never builds a view object.
