> Currently, ForeachBatchSink leverages ExternalRDD with converting
> RDD[InternalRow] to RDD[T], to provide Dataset[T] to the user function. This
> adds SerializeFromObject in the plan, which is actually not required.
> We can leverage LogicalRDD instead, to remove SerializeFromObject from the
> plan.
