Incremental Refresh for Datasets connected to Dataflow

Hi community , 

I  have used dataflow to connect to my datasource and my dataset is connected to dataflow. Since my data volume is huge I have configured Incremental Refresh for dataflow in the Service . Since my dataset is connected to this dataflow whenever refresh happens do it load all the data from the dataflow or Incremental refresh happens or do I need to configure Incremental Refresh as well for my dataset also
