LogicalRelation

case class LogicalRelation(relation: BaseRelation, expectedOutputAttributes: Option[Seq[Attribute]] = None, metastoreTableIdentifier: Option[TableIdentifier] = None) extends LeafNode with MultiInstanceRelation with Product with Serializable

Used to link a BaseRelation in to a logical query plan.

Note that sometimes we need to use LogicalRelation to replace an existing leaf node without changing the output attributes' IDs. The expectedOutputAttributes parameter is used for this purpose. See https://issues.apache.org/jira/browse/SPARK-10741 for more details.

    Returns a new instance of this LogicalRelation.

    Returns a new instance of this LogicalRelation. According to the semantics of MultiInstanceRelation, this method returns a copy of this object with unique expression ids. We respect the expectedOutputAttributes and create new instances of attributes in it.
