BaseSubqueryExec Physical Operators¶

BaseSubqueryExec is an extension of the SparkPlan abstraction for physical operators with a child subquery plan.

Contract¶

Child Subquery Physical Plan¶

child: SparkPlan

SparkPlan of the subquery

Used when:

• BaseSubqueryExec is requested to output, outputPartitioning and outputOrdering
• ExplainUtils utility is used to processPlan

Name¶

name: String

Used when:

• ReusedSubqueryExec physical operator is requested for the name
• InSubqueryExec expression is requested for the text representation

Implementations¶

• ReusedSubqueryExec
• SubqueryAdaptiveBroadcastExec
• SubqueryBroadcastExec
• SubqueryExec

Text Representation¶

generateTreeString(
  depth: Int,
  lastChildren: Seq[Boolean],
  append: String => Unit,
  verbose: Boolean,
  prefix: String = "",
  addSuffix: Boolean = false,
  maxFields: Int,
  printNodeId: Boolean): Unit

generateTreeString...FIXME

generateTreeString is part of the TreeNode abstraction.
