CoGroupExec

case class CoGroupExec(func: (Any, Iterator[Any], Iterator[Any]) ⇒ TraversableOnce[Any], keyDeserializer: Expression, leftDeserializer: Expression, rightDeserializer: Expression, leftGroup: Seq[Attribute], rightGroup: Seq[Attribute], leftAttr: Seq[Attribute], rightAttr: Seq[Attribute], outputObjAttr: Attribute, left: SparkPlan, right: SparkPlan) extends SparkPlan with BinaryExecNode with ObjectOperator with Product with Serializable

Co-groups the data from left and right children, and calls the function with each group and 2 iterators containing all elements in the group from left and right side. The result of this function is flattened before being output.

    Overridden by concrete implementations of SparkPlan.

    Overridden by concrete implementations of SparkPlan. It is guaranteed to run before any execute of SparkPlan. This is helpful if we want to set up some state before executing the query, e.g., BroadcastHashJoin uses it to broadcast asynchronously.

    Note: the prepare method has already walked down the tree, so the implementation doesn't need to call children's prepare methods.

    This will only be called once, protected by this.
