   @xudong963 @Dandandan These are good ideas. +1 on not using num of rows, and provide alternative logic to estimate size. I feel it make sense to add a size estimator to consolidate the logic. An additional thought - is it possible to get size (or estimation) from Arrow directly - I think this is one of the benefit Arrow format provides.
