EnsureRequirements

case class EnsureRequirements(optimizeOutRepartition: Boolean = true) extends Rule[SparkPlan] with Product with Serializable

Ensures that the Partitioning of input data meets the Distribution requirements for each operator by inserting ShuffleExchangeExec Operators where required. Also ensure that the input partition ordering requirements are met.

optimizeOutRepartition

A flag to indicate that if this rule should optimize out user-specified repartition shuffles or not. This is mostly true, but can be false in AQE when AQE optimization may change the plan output partitioning and need to retain the user-specified repartition shuffles in the plan.
