   @zhijiangW in what scenarios is the `RecordWriter` being used for broadcasting messages? I'm asking since it might not be worth paying the price of more complex code to support this. 
   
   Also I would be afraid that your proposed implementation of `RecordWriter` can behave worse in some scenarios with alternating broadcasted and not broadcasted messages compared to the previous version.
