> Currently, {{ExecNode#translateToPlan}} takes {{BatchPlanner}} or 
> {{StreamPlanner}} as a parameter, so {{ExecNode}} has a type parameter {{E <: 
> Planner}}, which indicates the node is a batch node or a streaming node. 
> While in the future, a plan may contain both batch nodes and stream node. The 
> type parameter can be removed, the implementation base class can cast the 
> planner to expected planner.
