1. case class BinaryHashJoinNode(conf: SQLConf, leftKeys: Seq[Expression], rightKeys: Seq[Expression], buildSide: BuildSide, left: LocalNode, right: LocalNode) extends BinaryLocalNode with HashJoinNode with Product with Serializable

   

   A HashJoinNode that builds the HashedRelation according to the value of buildSide.

   A HashJoinNode that builds the HashedRelation according to the value of buildSide. The actual work of this node is defined in HashJoinNode.

2. abstract class BinaryLocalNode extends LocalNode

   

3. case class BroadcastHashJoinNode(conf: SQLConf, streamedKeys: Seq[Expression], streamedNode: LocalNode, buildSide: BuildSide, buildOutput: Seq[Attribute], hashedRelation: Broadcast[HashedRelation]) extends UnaryLocalNode with HashJoinNode with Product with Serializable

   

   A HashJoinNode for broadcast join.

   A HashJoinNode for broadcast join. It takes a streamedNode and a broadcast HashedRelation. The actual work of this node is defined in HashJoinNode.

4. case class ConvertToSafeNode(conf: SQLConf, child: LocalNode) extends UnaryLocalNode with Product with Serializable

   

5. case class ConvertToUnsafeNode(conf: SQLConf, child: LocalNode) extends UnaryLocalNode with Product with Serializable

   

6. case class ExpandNode(conf: SQLConf, projections: Seq[Seq[Expression]], output: Seq[Attribute], child: LocalNode) extends UnaryLocalNode with Product with Serializable

   

7. case class FilterNode(conf: SQLConf, condition: Expression, child: LocalNode) extends UnaryLocalNode with Product with Serializable

   

8. trait HashJoinNode extends AnyRef

   

   An abstract node for sharing common functionality among different implementations of inner hash equi-join, notably BinaryHashJoinNode and BroadcastHashJoinNode.

   An abstract node for sharing common functionality among different implementations of inner hash equi-join, notably BinaryHashJoinNode and BroadcastHashJoinNode.

   Much of this code is similar to org.apache.spark.sql.execution.joins.HashJoin.

9. case class IntersectNode(conf: SQLConf, left: LocalNode, right: LocalNode) extends BinaryLocalNode with Product with Serializable

   

10. abstract class LeafLocalNode extends LocalNode

    

11. case class LimitNode(conf: SQLConf, limit: Int, child: LocalNode) extends UnaryLocalNode with Product with Serializable

    

12. abstract class LocalNode extends QueryPlan[LocalNode] with Logging

    

    A local physical operator, in the form of an iterator.

    A local physical operator, in the form of an iterator.

    Before consuming the iterator, open function must be called. After consuming the iterator, close function must be called.

13. case class NestedLoopJoinNode(conf: SQLConf, left: LocalNode, right: LocalNode, buildSide: BuildSide, joinType: JoinType, condition: Option[Expression]) extends BinaryLocalNode with Product with Serializable

    

14. case class ProjectNode(conf: SQLConf, projectList: Seq[NamedExpression], child: LocalNode) extends UnaryLocalNode with Product with Serializable

    conf

    the SQLConf

    lowerBound

    Lower-bound of the sampling probability (usually 0.0)

    upperBound

    Upper-bound of the sampling probability. The expected fraction sampled will be ub - lb.

    withReplacement

    Whether to sample with replacement.

    seed

    the random seed

    child

    the LocalNode

16. case class SeqScanNode(conf: SQLConf, output: Seq[Attribute], data: Seq[InternalRow]) extends LeafLocalNode with Product with Serializable

    

    An operator that scans some local data collection in the form of Scala Seq.
