  10. def columnMetadata(materializedColumnName: String): Metadata

    Column metadata to be used in conjunction QUALIFIED_COLUMN_NAME to mark row id columns

  11. def createBaseRowIdField(protocol: Protocol, metadata: Metadata): Option[StructField]

    The field readers can use to access the base row id column.

  12. def createRowIdField(protocol: Protocol, metadata: Metadata, nullable: Boolean): Option[StructField]

    The field readers can use to access the generated row id column.

    The field readers can use to access the generated row id column. The scanner's internal column name is obtained from the table's metadata.

  18. def isEnabled(protocol: Protocol, metadata: Metadata): Boolean

    Returns whether Row IDs are enabled on this table version.

    Returns whether Row IDs are enabled on this table version. Checks that Row IDs are supported, which is a pre-requisite for enabling Row IDs, throws an error if not.

    Any
  20. def isSupported(protocol: Protocol): Boolean

    Returns whether the protocol version supports the Row ID table feature.

    Returns whether the protocol version supports the Row ID table feature. Whenever Row IDs are supported, fresh Row IDs must be assigned to all newly committed files, even when Row IDs are disabled in the current table version.
