Delete from Hub
The Delete from Hub stage enables you to delete entities and relationships from a model. A dataflow that uses a Delete from Hub stage requires an input stage that contains data from or queries the same model whose elements you are deleting. It also has two optional output ports: one contains data for the deleted entities and relationships and the other contains data for the records that were not deleted.
To configure a Delete from Hub stage, you need to select the model you want to modify and then complete the Options tab and possibly the Runtime tab, depending on which write mode you want to use.
