PreprocessTableWithDVsStrategy

case class PreprocessTableWithDVsStrategy(session: SparkSession) extends Strategy with PreprocessTableWithDVs with Product with Serializable

Strategy to process tables with DVs and add the skip row column and filters.

This strategy will apply all transformations needed to tables with DVs and delegate to FileSourceStrategy to create the final plan. The DV filter will be the bottom-most filter in the plan and so it will be pushed down to the FileSourceScanExec at the beginning of the filter list.

    Transform all nodes matched by the rule in the query plan rooted at given plan.

    Transform all nodes matched by the rule in the query plan rooted at given plan. It traverses the tree starting from the leaves, whenever a SubqueryExpression expression is encountered, given rule is applied to the subquery plan plan in SubqueryExpression starting from the plan root until leaves.

    This is slightly different behavior compared to QueryPlan.transformUpWithSubqueries or QueryPlan.transformDownWithSubqueries

    It requires that the given plan already gone through OptimizeSubqueries and the root node denoting a subquery is removed and optimized appropriately.
