    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.
